Taylor Swift got an unwanted guest at her NYC building last month — an alleged stalker who was just arrested by the NYPD after he threatened to do harm to the singer … TMZ has learned.

New York law enforcement sources tell TMZ … Joshua Christian was booked Friday night for stalking after police tracked him down at his home following several run-ins with Taylor and her security personnel.

Our sources say Christian showed up uninvited to Taylor’s Manhattan home around 10:47 AM on June 12 with the “intent to annoy and harass” Swift.

We’re told Christian buzzed up to Taylor’s residence using the building’s intercom. When the superstar surprisingly answered, Christian allegedly threatened to hurt Taylor if she refused to be with him.

Taylor swiftly reported the incident to the police.

Kitti Jones — one of R. Kelly‘s exes who accused him of physical abuse and sexual coercion — says there’s only 2 ways he can fix himself … taking accountability and serious therapy.

Kitti says R. Kelly needs to accept the harm he’s inflicted on his victims and turn his life over to God … plus making the most of the mental health treatment he’s been ordered to undergo upon his prison release.

As we reported … Kelly was recently sentenced to 30 years in federal prison following his conviction for 9 federal charges, including sex crimes and human trafficking.

Kitti, who appeared in both ‘Surviving R. Kelly’ docs and gave a victim impact statement in front of Kelly at his sentencing, says she’s happy Kelly is off the streets so he can’t hurt more women.

Rihanna made her first official outing since becoming a mom, venturing out across the pond to support the new father and her partner, A$AP Rocky.

RiRi surfaced Friday at Wireless Fest in London, weaving her way through the crowd with her security detail as Rocky was performing on stage. She looks a little annoyed … but that might have to do with the screaming fans surrounding her.

Rihanna was wearing a black puffy jacket, Cuban link chain, hoop earrings and black leggings.

She was spotted in L.A. getting on a private jet for the U.K. with baby in tow, so looks like the whole fam is there.

TMZ broke the story … Rihanna and Rocky’s little baby boy was born on May 13 in Los Angeles.

Remember … Rihanna and A$AP announced her pregnancy back in January with a photo shoot in New York City, and RiRi proudly showed off her baby bump over the remainder of her pregnancy.

Jamie Spears flatly denies bugging his daughter’s bedroom … one of the most explosive charges leveled against her former conservator.

Jamie filed a declaration, obtained by TMZ, in connection with the ongoing battle over alleged misdeeds committed during Britney Spears‘ 13-year conservatorship, and he said flatly, “I am informed of the allegation by Britney’s counsel that a listening device or ‘bug’ was placed [in] her bedroom as surveillance during the Conservatorship. This allegation is false. I never conducted or authorized any surveillance of Britney’s bedroom at any time, including during the conservatorship.”

He went on to say he was not aware of any such device that was placed in his daughter’s bedroom.

The New York Times documentary about Britney’s conservatorship featured Alex Vlasov, a former employee of Black Box Security … the company Jamie hired. He claimed such a device was indeed secretly placed in her bedroom to spy … allegedly listening to private conversations.

Britney’s lawyer, Mathew Rosengart, has gone after Jamie hard, saying he violated his client’s privacy and civil liberties.

R. Kelly will be in his 80s when/if he gets out of prison, but there are still concerns the old man will remain a threat — especially to minors — so, he’ll have to live under a slew of strict conditions and counseling.

When Judge Ann M. Donnelly handed down Kelly’s 30-year sentence for federal sex crimes, she also ordered mental health treatment for the singer upon his release. According to docs, his treatment will include therapy for an unspecified sexual disorder, and he must avoid all contact with anyone under 18.

That seems like a no-brainer, considering how the disgraced R&B hitmaker ended up in prison — but there are even more criteria.

As we reported … prosecutors said Kelly is especially menacing to society, because he’d continued his criminal behavior for years after standing trial in Chicago for sex crimes. Seems that struck a chord with the judge, who ordered Kelly must inform anyone choosing to live with him that he is a sex offender.

The only way he’ll be allowed to be around someone under 18 is if it’s a family member, or it’s in a therapeutic setting with a “responsible adult” present — ditto for associating with convicted sex offenders. And, all of the above scenarios would first have to be approved by his probation officer.

He’s gonna get to know that P.O. very well — Kelly will remain under supervised release for 5 years once he gets out … and, that’s just for this sentence.

Bret Michaels is currently being treated in a Nashville hospital … a medical emergency that occurred just before he was set to get on stage with Poison.

The band is part of a massive stadium tour with Def Leppard, Motley Crue and Joan Jett. Audience members claim members from Poison got on stage Thursday night and let the crowd know Bret had to go to the hospital for a bad reaction to medication.

As a result, the other band members announced they wouldn’t be able to perform their set.

Obviously, some fans were upset, going to Twitter to express their disappointment. One fan wrote, “Came all the way from KC to watch poison. Bret Michaels was admitted to hospital. No poison in Nashville.”

Unclear how long Michaels will be sidelined, the tour continues with a date Saturday in Florida and Sunday in Mississippi.

Get well soon!!!

NBA star Miles Bridges was arrested for felony domestic violence in Los Angeles on Wednesday, TMZ Sports has learned.

The 24-year-old forward — who most recently played for the Charlotte Hornets — turned himself in to a local jail regarding an alleged physical altercation that happened on Tuesday.

Law enforcement sources tell us a woman claims she was in an argument with Bridges that turned physical. We’re told police were called to the scene, but Bridges was gone by the time cops arrived. We’re told the woman required medical attention.

The 6’7″, 225-pounder was arrested by LAPD after turning himself in Wednesday afternoon. His bail was set at $130k … and he’s since been released.

Bridges — who’s also a rapper under the name RTB MB — spent his first four seasons with the Hornets … but is expected to be a top free agency target this offseason.

Bridges was the 12th overall pick out of Michigan State in 2018 … averaging 13.4 points and 5.6 rebounds a game over 4 seasons. He had the best season of his career in 2021-22 … averaging 20.2 points, 7 rebounds and 3.8 assists.

Xzibit is ready to bury the hatchet with MTV parent company Viacom over his “Pimp My Ride” legacy — but says they first need to acknowledge he got screwed in the first place.

TMZ Hip Hop caught up with the West Coast vet after he unloaded on Viacom, claiming it’s essentially erasing him from the show’s history, and in the process, digging into his pockets!!!

X to the Z claims Viacom gave him the shaft by cutting his “image and likeness” from the show in order to get around paying him royalties over the years since the show was in production.

He says episodes cut for DVDs and streaming were also re-edited to remove his music, and DVD covers removed his image and likeness. We checked, and that tidbit appears to be true.

Xzibit was in his prime as a rapper when the show was shooting … laying platinum albums with Dr. Dre and hitting sold-out shows with Eminem and Snoop Dogg, and he says his celebrity boosted the show’s visibility.

In the suit, X calls Viacom’s actions “petty,” but he told us he’s willing to move forward and still hopes to conduct business with them down the line.

Calvin Harris is looking to dominate the Summer ’22 party waves with his “Funk Wav Bounces Vol. 2” album, and he’s enlisting several superstar rappers to get it done.

On Wednesday, the legendary DJ dropped a ‘Funk Wav’ teaser video, along with the A-list guest list which includes lots of rappers — like Pharrell, 21 Savage, Snoop Dogg, Pusha T, Lil Durk, Latto, Busta Rhymes and Swae Lee.

He’s also got Justin Timberlake and Shensheaa onboard for tracks … and the first single, “Potion,” arrived in May, featuring Dua Lipa and Young Thug.

Calvin’s 1st ‘Funk Wav’ was released back in 2017 … and earned a Gold plaque.

Sam Asghari says he’s still getting used to the fact Britney Spears is his wife, and to wearing a wedding ring — but he’s also keenly aware marriage has its benefits when it comes to his career.

Sam opened up about tying the knot with the pop star, calling their wedding day everything they’d imagined. He told ‘GMA’ … he and Britney wanted a fairytale and that’s exactly what they got.

The couple got hitched earlier this month at their former Thousand Oaks, CA home, and Sam says the intimate guest list of about 50-70 people was perfect — “We wanted to celebrate with, you know, our loved ones, our close people. We wanted to just celebrate, and that’s what we did.”

As for why SA was doing this ‘GMA’ interview … well, call it one of the perks of marrying Britney Spears — he was promoting his role in an action film, where he costars with Mel Gibson.

Sam says he’s grateful for any opportunities he gets because of Brit, but clearly doesn’t want anyone thinking he’s just riding her coattails. As he says, “Let’s not take away from the fact I’ve been working hard, and I was already acting.”
