Dating

"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 Lilly Ghalichi was 86'd from the show and now we've learned she's been replaced by Asifa Mirza -- a 32-year-old graduate school student living a pampered life courtesy of her retired ex-hubby, Bobby.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.

Lisa Leslie thinks there's nothing worse than being a little man, but says short guys should go after tall girls anyway ... just not her.

Leslie was doing a little food shopping Wednesday in Calabasas when our photog asked her if she had any advice for all the short guys trying to get with tall chicks.

Chrystal Workman continues making shocking claims in her bid to undo the court ruling that stripped her of custody of her daughter, Ariel Winter ... now she's raising strange allegations of sexual molestation.

Workman filed legal docs, obtained by TMZ, in which she claims her 15-year-old daughter has accused her of "sexual abuse or sexual molestation." Workman says, "I adamantly deny these accusations."

Here's the problem ... The "Modern Family" star has never hinted at sexual molestation in her guardianship case. She has only alleged physical and emotional abuse, so it's confounding as to why Workman is denying something that was never raised in court.

It's possible Workman is inartfully referring to an allegation by Ariel's boyfriend, Cameron Palatas, who said in his deposition, "Chrystal had wanted me to sleep in Ariel's bed." Palatas was an adult at the time.

'Real Housewives' star Adrienne Maloof goes through men faster than chili fries -- because right after we saw her spat with one much younger bf, she found herself a brand new ... much younger bf!

Cougars gotta eat.

It's great to be Adrien Brody.

The star of "The Pianist" was drowning in a sea of female flesh this weekend when he and hot girlfriend Lara Leito hit up a Turkish nightclub in Istanbul ... and couldn't resist the undulating charms of half-naked belly dancers who lured them onto the dance floor.

Brody's belly stayed hidden, however... he kept his clothes on.

Good news, single heterosexual men and/or lesbians: Eva Longoria (the sexiest 38-year-old woman on Earth) is now officially single.

Sources tell TMZ, the former "Desperate Housewives" star split from boyfriend Ernesto Arguello this week after dating for roughly 4 months.

The two met while Longoria was producing her dating show "Ready for Love." Ernesto was a bachelor on the program, but after the show went off the air, Eva decided to take Ernesto for herself.

Eva and Ernesto were spotted canoodling in Spain as recently as two weeks ago (above), but once they got back to L.A., we're told they decided their busy lifestyles just didn't mesh.

Eva spends most of her time in L.A., and Ernesto is situated primarily in Miami, so they decided it would be better to split. But some sources aren't convinced it's completely over -- as one source put it, "They're just on hold right now."

Translation: if you want to scoop Eva up, you better act fast.
