Celebrity Boobs

Former Playboy centerfold Kristina Shannon fell HARD multiple times, and damn near spilled right out of her top during a wasted night on the Sunset Strip.

Our photog caught Kristina mid-tumble as she was leaving the famed Chateau Marmont Thursday night -- and her poor friend was struggling to keep Shannon upright.

One half of the Shannon twins did manage to tell us about her new twins -- she says she got new boobs ... which she proceeded to flaunt, but that's not even the best part of this video.

Dr. Robert Rey is now killing two birds with one scalpel, if you will -- giving his patients bigger breasts without implants, and instead using unwanted fat and stem cells to get the job done.

The "Dr. 90210" star says he's doing implant surgery less and less these days -- and now up to 85% of his patients are opting for the stem cell breakthrough to naturally boost their racks.

It's pretty damn amazing ... watch the clip -- Dr. Rey explains how it works, and why he thinks it's better.

BTW ... this got us thinking about Paris Hilton -- who posted a revealing cleavage shot this week, but won't say if she had a boob job. God knows she could afford a few stem cells ... we just don't know where she'd get the unwanted fat.

Paris Hilton hasn't been very open about alleged massive changes to her boobs ... luckily her robe is plenty open.

While she's refused to talk about her chest ... she's still sharing A LOT of it in this super hypnotic selfie she posted.

Either Paris is REALLY good with makeup -- there's a lot of it in the pic -- or those whappers are doctor-enhanced.

Sure, her boobs were out ... but was it technically cleavage?

The gambling website that hosted the Katy Perry Super Bowl halftime boobs bet says the debate is raging in their office ... so they're just gonna pay EVERYONE!!

We broke the story ... BetOnline.ag hosted the bet and gave the following odds:

"Yes" is -500
"No" is +350

Translation -- if you bet "no," $100 gets you $350. If you bet "yes," you need to wager $500 to earn a measly $100.

So, when Katy dropped the flame outfit and switched to the chestier beachy look, you'd think it would be a victory for the pro-cleavage bettors.

But a rep for the gambling site says some people in the offices argued that since the boobs weren't pushed together, there was technically NO cleavage.

So, the decision was made ... the site has decided to pay BOTH SIDES of the bet.

Bottom line -- when it comes to Katy's boobs, there are no losers.

Chelsea Handler believes the God to whom you pray doesn't matter ... one thing's universal ... men of all faiths can appreciate a nice rack.

Handler has two things that can bring Jews and Muslims together and they're both on her chest ... she posted the topless Instagram pic -- with Star of David pasties -- while vacationing Wednesday in Israel.

This isn't her girl's first rodeo -- she swapped the camel for a horse and out-chested Vladimir Putin -- and pants also seem optional.

Katy Perry's boobs could make you A LOT of money -- because they've just become the focal points of a new Super Bowl prop bet ... TMZ Sports has learned.

The cyber-gambling site BetOnline.ag is offering up a bet -- where you can place money on whether you think Katy will show cleavage or no cleavage during her Super Bowl halftime show.

Right now ... the odds are STRONGLY for boobage:

"Yes" is -500
"No" is +350

Translation -- if you bet "no," $100 gets you $350. If you bet "yes," you need to wager $500 to earn a measly $100.

Some other prop bets?

-- The coin toss
-- Color of the Gatorade thrown on the winning coach
-- Hoodie type worn by Bill Belichick (sleeves vs. no sleeves)
-- Katy Perry's wardrobe at the beginning of Halftime (pants vs. shorts vs. dress or skirt)
-- Length of the National Anthem

... and get this -- you can bet on who Barack Obama will pick to win the Super Bowl.

Good luck.

Miss Beverly Hills Chanelle Riggan got something very important off her chest at the Miss California USA finals ... her top.

Depending how you look at it, Riggan suffered a major wardrobe malfunction during the bikini portion of the contest Jan. 11th, when her eager assets popped out.

That's one way to win, but the judges weren't as impressed ... after showing off those talents, she only managed to grab 4th runner up.

Jasmine Tridevil -- aka the woman who went around claiming she had three boobs -- was busted early Monday morning for suspicion of DUI, but her BAC wasn't three times the legal limit ... JUST TWO!

Tridevil (real name Alicia Hessler) was popped by the Hillsborough County Sheriff's Department in Tampa, FL at 3:47 AM. She was booked into the Orient Road Jail a short time later. The strip search must have been awfully interesting.

According to the booking info, Hessler's blood alcohol content was .180 and .178 in two tests ... each more than twice the legal limit in Florida.

She is currently still in custody and being held on $500 bail.

Tridevil made the rounds last September when she went around claiming to have a third breast. To the surprise of no one ... she turned out to be a fake.

Kim Kardashian was way ahead of the curve ... training a camera on herself when she was just 4.

We're told Kim's "Selfish" book contains pics she took of herself in the year George Orwell made famous. She picked up a camera and instinctively decided there was nothing better than photographing herself ... so she did.

Here's what Kim said in pitching the book, "I took pictures of myself with digital cameras when I was in junior high and high school, and I just got hooked." And this will shock you ... she says, "I was always obsessed with selfies."

And we're told ... the book was Kanye's idea. He titled it and his creative team -- Donda -- came up with the look.

It's due out in May.

Ain't no shame in her game ... there are two things "Shahs of Sunset" star Golnesa "GG" Gharachedaghi won't lie about ... and they're both on her chest.

GG wants the world to know she got a boob job last month -- we had a few questions for her outside of Beso in Hollywood ... but the only thing she'd dish on were those juicy new cantaloupes.

While flaunting her assets off she boasts " I don't lie about plastic surgery" -- an obvious jab at celebs like Kylie Jenner and Paris Hilton who've been called out for possibly having work done.

Gotta get them out there while they still have that new boob smell.

Tara Reid has a million reasons to rip off her clothes and have sex with a stranger -- a porn site likes what it sees and is offering big money for her to star in its next skin flick.

According to the offer, GameLink.com -- an on Demand porn site -- was so impressed by a sexy nude pic she posted on Instagram on NYE, it's ponying up $1M for her to, as they put it, "showcase her beauty and talent" by having sex on film.

Sounds like they only have her best interests in mind ... they're offering the 39-year-old an opportunity for her to tastefully explore her sexuality with full creative control.

No word yet if she'll accept ... but she could definitely squeeze one in before "Sharknado 3."

Kylie Jenner is scoffing at reports she got a boob job ... she's saying her busty Instagram photo is just the work of a fancy bra.

Our Kardashians sources say Kylie bought a new Victoria's Secret bra -- called Bombshell -- which increases your bust by 2 cup sizes. It's the bra Taylor Swift wore at the Victoria's Secret Fashion Show.

There are reports Bruce is upset over Kris allowing Kylie to get plastic surgery, but it's not true because she didn't go under the knife.

And, we're told Kris, Kim, Khloe and Kourtney thought the bra made Kylie look so good they ordered some for themselves.

It's confirmed ... Kim Kardashian isn't a terrorist ... but TSA just got all up in that bitch just to make sure.

Kim's five-alarm booty must have tripped the sensors Wednesday at a LAX security checkpoint ... she got the royal pat down by a female TSA officer while an annoyed Kanye West looked on.

It's unclear how long it took or what prompted it, but one thing we know for sure ... nothing fell between the cracks in this search.

It's a tale of two parents -- while Heidi Klum frolicked around topless in St. Barts with her boyfriend Vito Schnabel ... Seal took their kids to Mammoth for a ski vacation.

Heidi's moguls are the best around.

Miley Cyrus did not suffer a nip slip ... instead she offered a nip TIP to the world -- as in, GET YER YA YAS OUT -- and it instantly took over the Internet.

Miley showed out for the "Free the Nipple" campaign by posting a topless Instagram with a caption taunting people to report her whoppers-gone-wild. Surprisingly, it stayed up much longer than celeb nudes usually do. We're guessing Instagram takes holidays off too.

Miley also posted a series of mocked up -- and disturbing -- images of topless Hannah Montana to push the message ... which has also been touted by Chelsea Handler, Rumor and Scout Willis, and Cara Delevingne.

Miley's social media game is on point.

Much like Sony did with North Korea, Sharper Image has caved in its battle with the City of Las Vegas ... and in this scenario, Heidi Klum's boobs are "The Interview."

Sharper Image's new ad campaign features a scantily clad Klum alongside suggestive copy designed to get you to buy the gadgets Sharper Image sells that you never knew you needed.

But Klum's cleavage did not meet Clark County code and the ads were barred from being displayed at McCarran Airport. The crux of the problem ... "the showing of the female breast with less than a fully opaque covering or any portion thereof below the nipple" -- aka underboob.

So Sharper Image submitted toned downed pics, which were approved, and will soon be displayed for all to see.

Who knew Las Vegas was run by prudes?
