Lisa Lampanelli Check Me Out ... I'm F****** Skinny!

Lisa Lampanelli has pulled a Jonah Hill ... the comedian dropped more than a hundred pounds in the last year and now she's showing off her new bod.

Lisa posted the photo on Instagram today, more than a year after undergoing a sleeve gastrectomy -- a type of gastric bypass surgery. The progress is really impressive, but Lisa has insisted it's not a permanent fix. She still has to alter her eating habits to keep the weight off.

Skinny Lisa

We're proud of Lisa for the hard work, but when Jonah lost his weight ... there was a lot of talk that he was less funny because of it ... so we gotta ask ...

Heidi Montag Downsized Boobs From Mega-Huge to Huge

So long crazy F-cups ... Heidi Montag has unveiled her new C-cups after undergoing yet another breast-related medical procedure in October ... this time to REDUCE her breast size.

You'll recall, Montag famously underwent 10 plastic surgery procedures in one day back in 2010 -- including a mini brow lift, liposuction, buttock augmentation, Botox, a nose job, fat injections in her cheeks, nasolabial folds and lips, chin reduction, and increasing her breast size to F-cups.

Montag has publicly stated she regrets the procedures, and claims she got her breasts reduced because the enormous jugs were taking a toll on her happiness.

Montag says she was young and "unstable" when she got the procedures ... and now warns other girls about making the same mistake.

The Wanted's Max George My Hot GF's Got Crack Problems

Max George's girlfriend is truly a multi-tasker ... she can PDA and pick the thong out of her ass AT THE SAME TIME!!!!

Max -- the guy from The Wanted who once banged Lindsay Lohan -- took his hot model GF Nina Agdal to a beach vacation in the Bahamas ... where they galavanted around with their ridiculously attractive tan bodies.

They spearfished ... they yachted ... they boozed -- and most importantly, they documented almost the entire thing on camera so everyone could follow their half-naked vacay.

Sharing is caring.

Jessica Chastain I'll Get Naked for...

"Zero Dark Thirty" star Jessica Chastain has no problem getting naked -- she's just picky about where and when she does it.

Luckily, she just slipped ... and told us where to look.

Jessica Chastain I'M DOWN TO POSE NUDE ... But Not For Playboy

0-r9gdvnqo

Hugh Hefner's gonna be pissed ... 'cause "Zero Dark Thirty" star Jessica Chastain tells TMZ she's totally down to get naked in front of a camera ... but it will NEVER be for Playboy.

The Golden Globe winner was leaving the Brentwood Country Mart yesterday when we congratulated her on locking up the cover of Vogue -- and Jessica told us for her next shoot, she's hoping to do something a little more "risque.'"

Awesome.

So, naturally, we brought up Playboy ... but Jess shot that down hard -- saying, "I'll be naked in other magazines but not Playboy."

For the record, Chastain's not just talking the talk -- she's been naked in a couple of movies before "ZDT" ... including "Lawless" and "Jolene" ... the latter of which happens to be available on Netflix.

Chazz Palminteri's also in "Jolene" ... but don't worry -- he's totally clothed.

Britney Spears Video It Was 'Like an Orgy' ... Says Male Model

0-lgqqrw4s

Britney Spears was right ... the footage that was cut out of the "Work Bitch" music video was WAYYYY more erotic than the final cut ... so says one of the male models who was there.

We spoke with Richie Nuzzolese -- who played a hot shirtless guy in the video -- and he tells TMZ, "What's out in the video is only like half of what went down."

Richie tells us the scene he was in was "like an orgy ... very sexually oriented."

Nuzzolese says the scene -- which involved 15 super hot chicks -- was so intense, "it wasn't even like acting."

Damn.

Of course, Richie's description backs up Spears who said she felt like she was pushed too far sexually during the making of the video and personally CUT a bunch of content that was simply too racy for her.

Too bad ... sounds awesome.

'Teen Mom' Star Amber Portwood Post Prison Makeover From Slammer To Glamour

"Teen Mom" star Amber Portwood is no longer a prisoner to fashion... especially prison fashions ... and TMZ has learned she's embracing her freedom by creating a whole new glam look for herself.

After serving 17 months behind bars ... Portwood has freed herself from her harsh, mugshot makeup ... and is now showing off a post-prison makeover that gives her a softer, more sophisticated look.

Sources close to Amber tell us ... she's treated herself to a whole new set of clothes ... and a stylish new haircut.

But the biggest change ... they say ... she no longer uses homemade, prison-style hairspray (which is often made from Jolly Rancher candies because it's sticky and provides excellent hold).

So, the good news -- she looks great.
The bad news -- her hair no longer tastes like grape.

Drake vs. Chris Brown WHO'D YOU RATHER?

Here's the hairless 27-year-old Drake's new and improved shirtless picture that surfaced earlier today on a social media page (left) -- and an equally ripped and equally hairless 24-year-old Chris Brown showing off his permanent body art (right).

Only one of them is having anger issues in rehab.

The question is...

Drake Working Out is Working Out Shows Off New Physique

Drizzy Drake’s been on a fitness RAMPAGE … posing for shirtless pics in a Bieber-esque frenzy ever since he started dropping lbs for his new tour … and it looks like all the work is paying off.

Drake's trainer posted this latest installment on Instagram today … and he looks jacked with a noticeable four pack … and wearing an expression that says “even I’m surprised I look this good.”

No word on what inspired the new work out regimen ... but he's definitely starting to look more like Rihanna's type.

Bruce Jenner I'm Proud of Kendall's Boobs

Kendall Jenner doesn't need a bra ... because her own father fully supports her breasts.

Sources close to Bruce Jenner tell TMZ, he 100% backs his 18-year-old daughter's decision Tuesday to expose her nipples on Instagram. As far as he's concerned, she's a fashion model ... and that's what fashion models do.

Soon after Kendall posted the pic for her 7 million followers, Bruce began defending his daughter ... saying she's a "wonderful kid and a great daughter" ... and insisting he's proud of her no matter what she does.

Just so we're all clear ... Kendall turned 18 on November 3rd. We're proud of her too.

Kendall Jenner I'm 18 ... So Here are My Nipples

After only 16 days since her 18th birthday … Kendall Jenner decided to give the world a glimpse of her nipples … leaving everyone wondering ... what took so long?

Who'd you rather?

Kendall posted the pic on Instagram today ... she's wearing a sheer black top … leaving no doubt she's now officially in the Kardashian game of selling sex.

Now here's the question ... does it all end with nipples, or will Kendall walk the path forged by her older sister, with the helping **** of Ray J?

And while we're at it ... we gotta ask ...

Bar Refaeli First Post-Surgery Bikini Sesh

Guess Bar Refaeli is feeling better after going under the knife ... 'cause hours after she had a mole surgically removed from her torso, the supermodel was galavanting around in her bikini.

Bar originally posted a pic in a doctor's office on November 12 -- with the caption, "Goodbye beauty mark." It's unclear why the 28-year-old had the mark removed.

But hours after the procedure, Bar posted another couple of shots ... showing her running around the beach in a bikini with a bandage on the spot where her mole used to be.

Supermodels -- they even make recovering from surgery look easy.

Paulina Gretzky 3rd Degree Burns Wouldn't Keep Us Away

Wayne Gretzky's unbelievably beautiful daughter Paulina nearly bit the dust when her sweater caught fire at a bar -- which means we almost lost the hottest celebrity spawn on planet Earth.

Here's the reportedly 6'1" American made super model Karlie Kloss (21) towering over the reportedly 5'11" Brazilian bombshell -- and mother of two -- Gisele Bundchen (33) at an awards ceremony in New York City last night.

They're both tall -- but the big question ...

Kate Upton Naked. Body. Paint.

Here's Kate Upton ... basically naked ... with some strategically placed body paint.

You're welcome.

Kate got all painted up for a Sports Illustrated photo shoot -- in the footage, Kate's trying to recreate one of the mag's most famous Swimsuit Edition covers.

We think she nailed it.

"I definitely feel naked," Kate said during the shoot ... "Because I am."

Kate said the artists took a particularly long time to paint on the necklace on her boob area ... yeah, can't imagine why.
