Dating

It's official ... NY Knicks star Iman Shumpert's in a full-on RELATIONSHIP with singer Teyana Taylor -- and TMZ Sports has the video proof.

There had been rumors the two were hookin' up, but this week the two set the record straight -- hitting up "The Equalizer" premiere together in NYC ... with all sorts of PDA.

Check out the clip -- Iman bristles at the notion that their relationship was fake and solidifies the union by dropping the all important "bae" when referring to Taylor.

BONUS -- they even had their very first couple's activity ... teaming up to interview "Power" star Naturi Naughton right on the street.

With French Montana on the outs, Khloe Kardashian was reunited Monday night with the guy she always seems to turn to during breakup times ... The Game.

Khloe and Game have been BFFs for a while and dating rumors swirled when she and Lamar Odom split ... but they insist it's strictly platonic.

Our photog spotted the pair leaving the Topanga Mall where Game said he loves Khloe's new cornrows.

Tim Musomba -- who will appear on Showtime's "Shameless" this coming season -- is calling out a star on Showtime's "Ray Donovan" for being "a little on the creepy side" ... because he's dating a barely legal girl.

Musomba was leaving Mastro's Thursday night when we asked him about the reported romance between the 57-year-old Steven Bauer and 18-year-old Lyda Loudon.

Tim is hilarious ... his first thought is that because this is L.A. ... if you are a fit 57 there's no problem. But then he thinks harder.

You gotta watch the video. It's great.

Paris Hilton probably gets hit on all the time ... but it's rare when a homeless lays the mack down.

Paris was leaving Tao restaurant in NYC when she stopped to give some cash to a homeless guy -- and that's when the dude saw his chance to spit some game.

He kissed her. He smooth-talked her. He asked her out on a date.

And for the record ... she didn't exactly say 'No.'

Taylor Swift believes Katy Perry is a thief ... and we've learned that's the basis of their feud.

The girl-on-girl war ignited when 3 of Taylor's dancers jumped ship and joined Katy's tour. Taylor felt betrayed because she became very close to the dancers and considered them family.

But here's the thing. The 3 dancers had actually worked with Katy first, but when Katy's tour ended several years ago they needed work. So they signed up as dancers during Taylor's tour.

We're told the dancers told Taylor up front ... they did not want to sign for the full tour -- they wanted a 30-day out, and we're told it's because they were just waiting for Katy to go back on tour.

When Katy hit the stage again, they gave their 30-day notice, but Taylor got so pissed off she fired them on the spot.

All of this went down a year ago but we're told Taylor held a grudge, which boiled over when she wrote a song -- "Bad Blood" -- alluding to Katy screwing her over.

It's turned into a full on war, with Taylor not-so-coyly talking about the alleged betrayal -- and Katy responding on Twitter by calling Swift ... Regina George in sheep's clothing.

"Shahs of Sunset" producers are adding more sex and drama for the upcoming 4th season ... by hiring a new chick ... who's trying to remarry her ex-husband.

TMZ broke the story ... Lilly Ghalichi was 86'd from the show and now we've learned she's been replaced by Asifa Mirza -- a 32-year-old graduate school student living a pampered life courtesy of her retired ex-hubby, Bobby. As for the sex and drama -- Asifa and Bobby divorced after 14 months of marriage .... yet they're currently banging again. Who says you can't go back?

We're also told GG's gonna have a major storyline, too -- accusing Mike of trying to have sex with her in Turkey last year -- and even submitting to a lie detector test.

Lea Michele's new boyfriend isn't a fun summer fling after all ... officially ditching his gigolo lifestyle in order to move in with the "Glee" star full-time ... TMZ has learned.

Sources close to Lea tell us ... Matthew Paetz packed his stuff into a U-Haul over the weekend ... moving out of his apartment, and upgrading to her $1.4 million Hollywood pad after just 4 months of dating.

We're told Paetz already had a toothbrush and a few t-shirts at her their place ... but now everything's been moved -- rugs, furniture and even his pillows.

If you can't execute a rear naked chokehold, you're looking at a group of chicks you have no chance of scoring with ... ever.

TMZ Sports spoke with the cast of UFC's "The Ultimate Fighter 20" (which starts next week on Fox Sports 1) ... bona fide bad ass chicks ... who tell us they only date dudes who are as deadly as they are.

The lovely (and lethal) ladies were out in NY when we asked them if guys are (rightfully) intimidated by them ... being they could prolly beat up most of the Earth's human population.

Peep the clip -- the ladies make it clear the type of men they date would never be intimidated by ANYONE.

David Lucado says he didn't technically cheat on Britney Spears ... because his videotaped hookup with another chick went down AFTER Brit had already kicked him to the curb.

Lucado is telling friends Britney dumped him via text on August 6th. Sources close to the ex couple tell us they'd been arguing over "outside influences" -- like her conservators -- who control Britney's life ... and Spears sent him a message saying, "I'm done with you."

Lucado's cheating sesh went down the very next night on August 7 -- and as we first told you Britney's dad now owns the video of the hookup. We're told David and Brit reconciled, conveniently, on August 8.

Sources close to David tell us he wants to get in touch with Britney to pitch his "we were on a break" theory. But as we previously reported ... Papa Spears and everyone else around Brit ain't about to let that happen.

Kim Kardashian gave Rita Ora the cold shoulder at the VMAs last Sunday -- refusing to sit near her -- and sources close to the family say it's because Kim blames her for screwing with Rob Kardashian's head.

We're told Kim arrived at the awards show and discovered her seat was just a couple away from Ora's. Not wanting any drama ... she asked producers to find her a different seat. We're told she wasn't a diva, she just didn't want to have to be social with Rita.

Sources close to the Kardashians tell us the family still blames Ora for some of Rob's issues ... since his ugly breakup with her in 2012.

VMA producers had to scramble, but ultimately they found a seat for Kim ... with Kendall and Kylie.

Britney Spears just dumped her boyfriend of 18 months ... after finding out there's a video of him cheating on her that's being shopped around Hollywood.

We're told David Lucado is seen in the video making out with a woman and dancing with her. It looks like they're in someone's living room. We're told the video was shot in early August.

When we called Lucado ... a rep told us, "David is very, very in love with Britney. This is unfortunate and he hopes that it all works out."

Well, it didn't. We called Britney's camp for comment, and we were told her father Jamie wanted to say something about it, but wanted to tell Britney first. It appears as soon he told her ... she broke up with David.

She just tweeted, "Ahhhh the single life!"

Congratulations to Al Pacino's smoke show of a girlfriend -- she actually found a way to upstage the acting legend ... simply show off your ridiculous body in a see through top!

Pacino and Lucila Sola strolled through JFK airport Wednesday. The 35-year-old Argentinian actress has been dating 74-year-old Pacino for a couple years now.

Lucila made it blatantly obvious why Al was sporting a sly smile.

And ya just know the answer to the question we're all thinking is ... yes, she does.

Riff Raff tried telling us he was dating Katy Perry months ago and we didn't believe him ... but Sunday night, the two looked like quite the couple -- the key word being ... LOOKED.

Following the VMAs, our photog spotted the happy couple leaving Mastro's wearing matching denim outfits. They were both clearly tipsy and joked about picking baby names.

But when you see the car door close ... and Katy's hand press against the window -- this all starts to look like they're both trying way too hard. It's not that we don't want RR to land a chick like Katy ... it's just that their gushing stinks of a publicity stunt.

Back in March, Riff Raff told us he and Katy were a thing, but check out the other girl in the video ... we assumed he was just kidding. Based on last night's video, we were probably right.

Chris Brown says he's back with Karrueche because she finally realized he did NOT have sex on a St. Tropez yacht.

The on-again-off-again couple is now on again ... and Chris says it's because Karrueche now realizes he was telling her the truth when he said he was not having sex with anyone else.

Sources close to Karrueche tell us ... he was frantically texting and calling her -- more than 20 attempts a day -- to acquit himself, but she ignored him.

We're told Saturday ... Karrueche showed up at Chris' celebrity flag football game to talk it out ... which they did, and she believes him.

As for the whole yacht thing ... there definitely was smoke ... he was on the vessel cavorting with several women, including one of Karrueche's close friends.

Barry White would be proud ... Justin Bieber and Selena Gomez can't get enough of their love -- TMZ has learned they're back on for the umpteenth time.

Sources close to Jelena tell TMZ ... the two are trying to work things out. We're told they even went to church together Wednesday night, and they're "trying to be better people."

Not coincidentally, Bieber posted a Bible verse on Instagram the next day that read, "After you have suffered a little while, God will restore, confirm, strengthen and establish you."

They were also spotted at the movies earlier this week and Justin posted (and quickly deleted) a photo that appeared to show Selena kissing his cheek.

Yes ... we're getting ready for a "Justin and Selena Break Up" story. Again.

U.S. Olympian Joshua Mance's dream of bangin' a porn star could still be alive -- 'cause one of the hottest women in the flesh biz tells TMZ Sports she's willing to give him a shot at her gold medal.

We shot Josh a few weeks back, and the Olympic silver medalist made an impassioned plea for us to hook him up with porn star Skin Diamond -- which didn't exactly work out.

But sometimes when one door closes, another hole opens -- because Courtney Taylor tells us she saw our video of Joshua, and thinks ..."He is super cute. I'd be all about that boy."

Courtney -- star of "Art Of Anal 2" and "Interracial Swingers 1" -- says she's ready to introduce Josh to her style of banging, telling us ... "Trust me, he'd love his first porn star experience."

Ball's in your court, Josh ... until Courtney gets a hold of 'em.
