Celebrity Boobs

Kourtney Kardashian and Scott Disick snuck away for a weekend trip to Mexico without the kiddos.

The on again, off again, on again couple hit up Cabo ... days after they visited their new niece, Dream Kardashian.

This topless pic of 'Real Housewives of Orange County' star Vicki Gunvalson has triggered an FBI complaint, and the agency is now looking into it ... TMZ has learned.

The pic was taken in Dublin, Ireland where cast members were on a retreat. Production sources say Tamra Judge took the pic and sent it to other cast members and producers with some snarky comments.

Somehow, the photo ended up on the social media account of a 15-year-old girl, who tweeted it out.

A woman named Rosalie saw the photo and filed a complaint with the FBI, saying "Tamara Judge ... sent a nude photograph of an acquaintance of hers (taken at a small gathering) to a FIFTEEN YEAR OLD girl & asked her to distribute it online in an effort to humiliate & harass one Vicki Gunvalson."

We reached out to Tamra ... sources close to her tell us she didn't leak the photo or in any way facilitate it getting into the hands of a minor.

The FBI is evaluating it but has not yet opened a formal investigation ... law enforcement sources tell us.

As for why Vicki posed topless ... fellow castmate Heather Dubrow was FaceTiming her hubby, "Botched" plastic surgeon Terry Dubrow, and Vicki wanted him to examine her nipples, which she felt were uneven.

Celebs were out in force in Hollywood Saturday night, and they didn't fool us.

Abigail Ratchford certainly was hiding in plain sight. Kylie Jenner was true to form, dressing as Christina Aguilera in the "Dirrty" vid, which is hot.

As for Tyga ... well, he dressed as a successful rapper, Juelz Santana.

Check out Matt Bellamy, Elle Evans, Tera Reid, Kate Hudson, Taylor Lautner, Kourtney Kardashian, Paris Hilton, Joanna Krupa, Nick Jonas, Sofia Richie and more.

Snapchat queen YesJulz showed off the 3 B's Saturday in Miami ... bathing suit, butt and boobs.

Not much else to say.

Great news -- Kylie Jenner's future is trending damn near nude ... at least based on the futuristic photo shoot she just did.

Kylie is the cover girl for Complex's October/November issue, and her spread features nothing but latex. Oh, and some Pokemon-ish imagery too. But yeah. Latex.

There's an article too -- if you care -- and she talks about Tyga and lip injections. Blah, blah, blah ... latex. Complex teamed up with famous Japanese artist Takashi Murakami for the shoot.

Christina Milian in a see-through dress -- need we say more?

Fine.

The singer celebrated her 35th birthday at Catch in WeHo and was transparent as ever after her friends pulled off a surprise party. Check out the vid ... she's the gift that keeps on giving.

Victoria's Secret Angel Stella Maxwell -- Miley Cyrus' old hookup chick -- either broke or embraced rule number 1 by rolling up to the Love Magazine party in London Monday night braless in full boob glory.

It's one way to stick out in a crowd that included Bella Hadid, Rocco Ritchie, Kate Moss, Courtney Love and Frances Bean, Cara Delevingne and Rosie Huntington-Whiteley.

Louisiana-bred model Lindsey Pelas doesn't need a lifeguard watching over her as she wades in the Pacific.

Emily Ratajkowski's boobs were holding on for dear life at Fashion Week.

The model gave her pair quite a breather while attending Harper's Bazaar's "ICONS By Carine Roitfeld" celebration over the weekend at The Plaza Hotel in NYC.

Monday's off to a great start ...

Lady Gaga's full of crop tops in London, which means she's letting almost everything hang out.

Gaga left Capital London early Friday morning with a giant denim wedgie -- and cup of coffee.

She's got a new song out, and if this is how she's gonna promote, we say ... keep plugging away, Gaga!

Kim Kardashian's lucky to have Kanye West as a husband ... because he has a great eye for fashion.

We got Kim and Kanye making their way to dinner in SoHo Monday night where Kim was looking white hot in a low-cut blouse and jean skirt, with a long coat struggling to provide cover ... all in vain.

Director Paul Verhoeven is proof inspiration strikes in species everywhere -- like dog nipples for the 8-breasted hooker he wanted for "Total Recall."

The famed director -- who also had a hand in classics like "RoboCop" and "Starship Troopers" -- dished LOTS of details when we caught up with him Thursday night in L.A. Check out the vid ... he's seriously fixated on boobs.

We couldn't leave without settling a huge puzzler in "Starship Troopers" -- is the big alien meant to look like a vagina?

Take a look.

Two airports in Cali want Mariah Carey's boobs up out of their faces -- they're banning the billboards she commissioned because they're way too sexy.

Mimi's returning to Vegas later this month, and to promote the show we're told she shelled out thousands for an inviting photo shoot that were going up on billboards near Burbank and Orange County airports -- huge takeoff spots for the Vegas-bound L.A. crowd.

Problem is ... the airports have big issues with Mariah's boobs, barely covered by a gold sheet. We're told even Caesars, where Mariah will be performing, wants a censored version of the billboard.

Mariah, we're told, is pressing for the original in all its glory.

We're with her.

Think Usain Bolt is having fun at the Olympics??

LeAnn Rimes let it all hang out -- or at least most of it -- at a gay nightclub in London.

Rimes performed at G-A-Y Saturday night, and she looks pretty fantastic.

Among the songs she sang -- "How Do I Live." The answer ... clearly without a bra.

Two Wilhelmina models got down and dirty ... which would explain the wet t-shirts.

Ashley Robbins and Nereyda Bird flaunted their stuff Tuesday during a Miami photo shoot.
