Nudity

Rob Gronkowski went on "Jimmy Kimmel Live!" Thursday night and said he was NOT fully naked during the GQ photo shoot ... despite what TMZ Sports reported -- but it's a curious situation.

We reported earlier in the day that RG was in his birthday suit during the racy boat photo with supermodel Hailey Clauson -- but only after a GQ publicist squarely told us in an email, "Yes, he was naked."

Hours later, Gronkowski refuted the claim on 'Kimmel' -- saying he was wearing a tiny Speedo that covered his junk.

We called the GQ rep back -- and spoke with her boss (the communications director for GQ) who gave us 3 different and intriguing explanations.

First, she said Gronk was "definitely naked on some parts of the shoot."

Then she said, "The info I got is what I gave you" ... suggesting there may have been a cover up over not covering up.

Finally, the plot totally thickened with her 3rd point -- "Maybe he didn't want to talk about being naked on Kimmel."

9:23 AM PT -- We asked GQ if Gronk was really fully naked for the shoot.

The answer -- "Yes, he was naked."

Boom.

So, here's a pic from Gronk's highly anticipated GQ article ... in which the photo shoot motivation was apparently, "Surprise! Here's my dong!"

The flashee in the shot is supermodel Hailey Clauson -- who teamed up with the Pats tight end for the cover of the upcoming June issue of the magazine.

The guy who wrote the article about Gronk spent some time embedded with the NFL star and described his life the following way:

"Gronkowski seems to exist in a permanent shower of champagne spray and nightclub-foam-party foam ... all without ever seeming like a creepy douchebag.”

Alessandra Ambrosio's so damn hot she turned a wardrobe malfunction into a work of art.

The Brazilian supermodel looked flawless at a secret beach photo shoot, despite the peekaboo. Check out the photos, and thank God for wind.

Usher just broke the cardinal rule of taking a naked selfie by posting a tad bit more than he probably realized on Snapchat.

Ursh snapped the pic Thursday and captioned it "blowin off steam" with an emoji covering his junk. Upon closer look it was hard to ignore that the emoji failed to cover all of his man parts and the tip of his dong was left sticking out.

We had to retouch it a bit since it's technically a d*** pic, but you can use your imagination and probably Google and find the real thing.

"Strong" trainer Adam Von Rothfelder has become instantly famous as the breakout star of the new show ... so like half of Hollywood it's not a big shocker nude photos have surfaced.

Turns out Adam posed nude for an art project and the pics are ... impressive. The honchos on "Strong" were a little upset ... not because of the pics but because Adam didn't fess up before he was hired.

We're told Adam explained he didn't think it was a big deal because it's not pornographic. Producers saw it his way, so he won't be punished. It helps he's also a big reason people are watching.

Dave Broome -- the creator of 'Biggest Loser' and "Strong" -- is a big, big fan of Adam's work ... telling us, "I am actually rather envious."

Justin Bieber just gave fans two reasons to smile ... posting a pic of his bare cheeks on Instagram.

JB put the pic up Sat. night with the caption, "Dat ass doe." It's unclear where the pic was taken, but one thing's for sure, it's breathtaking.

So, Vader's naked penis was unleashed on the world Friday via Twitter ... but the ex-WWE superstar says it was a MISTAKE -- and he's pointing the finger at a vengeful ex-girlfriend.

The pic of Vader's junk was quickly removed from his Twitter page shortly after it went public -- and the 60-year-old was quick to explain how it happened.

"I want to apologize to everyone. My ExGirlfriend hacked my account and sent out an inappropriate picture. Please except my apology."

Brittney Griner wants the world to know she's proud to be a member of the I.B.T.C. ... taking to social media to smack all the haters body shaming her for a lack of boobage.

It began when Griner posted a picture of herself in a cut off tee shirt which exposed a little side boob. It wasn't enough side boob for some ... and she was clowned in her comments section for cup deficiency.

Griner swung back with her very next post ... putting up a partially nude image of herself and an accompanying caption addressing anyone who has an issue with her girls.

"I love being naked and I don't care people seeing this bird chest of mine and making fun of it! Go head! I love myself and I love my body!"

Good job Brittney ... we would say A for effort ... but we don't want any beef.

A hockey player drafted by the Chicago Blackhawks is being prosecuted over revenge porn -- after officials say he shared a sex photo of a woman he should have known was not meant for other eyes.

Kim Kardashian is naked on your screen once again.

The mother of two bared all for no reason in a selfie, which she captioned, "When you're like I have nothing to wear LOL."

It's doubtful the photo was shot recently, since she's blonde in the pic and her post-baby body is probably not THAT amazing ... yet.

It looks like it was taken last year around the time of Paris Fashion Week.

Anyone complaining? We didn't think so ...

Turns out a little penis (not really) can take you a long way ... or at least for NFL prospect Chris Jones ... whose combine wardrobe malfunction just netted him a year of free undies!!!

By now you've seen the video ... the big DT from Mississippi State had a little mishap during his 40 ... falling flat on his face ... and flashing a little (not really) frank & beans in the process.

Well PSD underwear wants to make sure that never happens again ... and President Curt Flaitz tells TMZ Sports they plan to keep Jones' boys snug ... by sending him some testicular backup.

“I reached out to Chris Agent and I am sending him a year worth of PSD Underwear today“

PSD is a big deal in the sports world ... the company is owned by NBA stars Jimmy Butler, Chandler Parsons and Kyrie Irving.

They must work ... we haven't seen those guys' junk yet ... happy dashing Chris.

Jane Krakowski put it ALL out there -- boobs and butt included -- for a lounge singer styled performance totally reminiscent of her "30 Rock" days.

Jane was the showstopper of the night at a gala for the Roundabout Theatre in NYC on Monday ... and never missed a beat when her full ass crack and nipples were exposed.

Ted Cruz could fill his campaign coffers with a million bucks ... with a teeny tiny string attached -- he has to star in a porn flick.

As you probably know, back in the day, Ted rhapsodized about starring in a "teen tit film."

Well, not unexpectedly, Vivid Entertainment honcho Steve Hirsch has extended Mr. Cruz an offer to star in an XXX film -- far more graphic than an '80s boob movie. Hirsch suggests the title, "Cruzin for Bush."

He's willing to donate $1 mil through the Super Pac of Ted's choice.

Beyonce's boobs could get you seriously paid -- 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 Bey will release her two single ladies during her halftime performance with Coldplay.

Right now ... the odds are heavily in favor of Bey's girls showing up.

Yes -350
No +260

(Translation -- you have to bet $350 on "yes" just to win $100).

If boobs aren't your thing ... there are some other prop bets.

-- Does Osweiler play?

-- Color of the Gatorade bath.

-- And of course ... the coin toss.

Male model Shaun Ross looks like he illegally poached an elephant trunk in a new music video -- which has the Internet buzzing -- but chill folks ... it ain't what it seems.

Shaun does FULL frontal nudity in Braves "Dust" video, and while the size of his junk is jaw-droppingly shocking -- sources close to the model tell us Shaun wore a prosthetic over his real crown jewels.

We're told the director was going for art and shock value, and we gotta say ... nailed it! If you wanna see the prosthetic artist's handiwork ... go ahead and click.

The "Dust" music vid is 3 and a half minutes of Ross walking out of the ocean in slo-mo, and the massive faux dong only appears in the last 30 seconds or so.

No word on exactly how long the fake junk is, but we'll say this ... all of our censor tape is necessary. As one person in our office put it, "It looks like it zigzags when it swings."

Tammy Sytch is licking her chops at the release of her celeb porn video that hit the Internet Monday and challenged former wrestler turned porn star Chyna to a match.

Now that she's prime time in the porn world, Tammy's taking the opportunity to challenge her friend Chyna, telling us ... "without a doubt she can kick my ass in the wrestling ring, but I really don't think she stands a chance against me where it matters most. In the bedroom."

Tammy's feeling confident, now that her Vivid Entertainment video "Sunny Side Up" is live on the web, but remember ... Chyna is no stranger to the porn ring.

Tammy even gave her the option of either a one-on-one sex match or they could bring in a man and see who taps out first.

Let the games begin!
