Celebrity Boobs

Mario Lopez's 2-week wife Ali Landry is an expert on her knees, easily keeping her balance during a smoking hot paddle boarding session in Hawaii earlier today.

In case you forgot, Mario and Ali were married on April 24th, 2004. Their marriage was annulled two weeks later.

She's no stranger to weird get-ups, but "Tik Tok" singer Ke$ha took it up a sexy notch by wearing some sorta revealing leather one-legged bathing suit type thing on the set of her "Die Young" music video in L.A. on Wednesday.

It's awards season ... so naturally, Christina Hendricks' boobs dolled themselves up for a big night out at the Emmys!!

The boobs sat at a table with their "Mad Men" co-stars ... while sipping on champagne and snacking on some fancy desserts. They didn't win an award, but still a great time was had by all.

Sources say Christina was there too.

Heidi Klum is totally cool being topless (like most Europeans) but she is adamant that snapping half-naked shots of her in the privacy of her own home is a HUGE NO NO ... sources close to the model tell TMZ.

As TMZ first reported, Heidi is considering filing a lawsuit after topless photos of her were printed in France. Klum is peeved because the photos were taken at her home, on a private beach.

We're told it's that fact that has Klum particularly peeved. Our sources says Klum has no problem being photographed topless when she goes on a public beach, but it's not okay when she's on private property.

According to our sources, Heidi says the cameramen were literally hanging from trees, using long range lenses (from miles away) and sending helicopters to fly over the house in order to get the shot.

We're told Heidi is furious that these private images -- which included her small children -- were blasted all over the world for everyone to see and even ended up on porn websites.

Heidi Klum is really upset over brand new topless photos that have been published in a French magazine ... claiming her privacy was violated a la Kate Middleton ... and now she's seriously considering filing a lawsuit.

The photos have surfaced on several websites ... showing Heidi on vacation in the south of France with her bodyguard boyfriend ... sans bikini top.

There's just one problem ... it's unclear which French magazine published the original pics.

Sources close to Heidi tell TMZ ... the supermodel's camp is on the hunt for the source publication ... claiming her right to privacy was violated because she was on a private and secluded beach at the time the pics were taken.

Sound familiar? We're told Heidi is comparing her situation to that of Kate Middleton ... who also believes she was the victim of privacy invasion when a paparazzo snapped topless pics of her while she was sunbathing at a private chateau in France.

We're told ... just like Kate, Heidi wants to sue someone's ass ... but realizes she might have better luck if she waits for Kate to blaze the legal trail.

Long story short -- if Kate's legal attack is successful, Klum can simply copy her playbook ... and if it's not, she can learn from Kate's mistakes.

The 27-year-old mother of one is very, very good for the environment.

Leonardo DiCaprio's latest supermodel girlfriend Erin Heatherton showed off her sexy curves in a glorious bikini in Miami this weekend.

The ridiculously hot 23-year-old Victoria's Secret Angel even attempted to cool things off by taking a dip in the pool.

Rihanna got a new tattoo directly underneath her boobs ... setting off alarms with the censors, and raising 2 important questions: how much underboob is too much, and how will this affect Kate Upton?

Tom Arnold says tattooing Roseanne's face on his chest back in the day was the stupidest thing he's ever done -- this from a guy who once did a film called "Homo Erectus."

Arnold tells TMZ ... he got the tat back in 1994 in a last ditch effort to save his marriage ... but obviously his plan failed, big time.

In fact, Tom says he had to suffer through a year-and-a-half of painful lasers to get rid of the ink knowing ... "I'd never have sex with anyone until I got that removed."

But Tom's affair with STUPID tattoos didn't end with Roseanne -- the actor says he got Chinese characters on his leg years ago, because he thought it meant "love of mankind."

Turns out ... he was wrong ... at least according to Tom's "Cradle 2 the Grave" co-star Jet Li ... who translated the tat ... and said it means something totally different and way more hilarious.

Check out the video -- pretty funny stuff.

Steven Tyler got an X-rated peep show at a clothing optional beach in Maui this weekend ... but the former "American Idol" judge kept it strictly PG by leaving his fancy women's palazzo pants on amongst a sea of bare-ass sunbathers.

The 64-year-old Aerosmith front man is so enamored with the silky slacks that he was spotted still wearing them the very next day.

Jessica Simpson has two huge obstacles to overcome on her quest for her old bod ... her giant boobs ... 'cause Jessica says they've gotten so big, she can't go running.

Simpson is finally discussing her tremendous weight gain to People.com, claiming she packed on the pounds during her pregnancy because "It was the first time I was ever pregnant, and I wanted to enjoy it."

Jess says she loaded up on mac and cheese and other crap that's delicious but terrible for you ... because "I didn't realize [the weight] didn't all come off with the baby."

Of course she didn't.

Now, Simpson is working out with a fancy Hollywood trainer ... but refuses to go running because she doesn't want to end up with two self-induced black eyes ...saying, "My boobs are way too big to run at this point."

Despite all the fatness, Simpson is committed to revealing her new, skinnier, Weight-Watchers assisted body on September 10 ... on Katie Couric's new show. Can't wait.

Unlike the bloodless vampire she plays on screen, 24-year-old "Twilight" star Nikki Reed showed off her sexy tan in Hawaii this weekend ... wearing a smoking hot bikini while on a stroll with her husband.

(Fun fact: Nikki's husband is former "American Idol" contestant Paul McDonald, who placed 8th on Season 10.)

Supermodel Bar Refaeli showed off all of her ridiculously amazing talents in a sexy two-piece swimsuit on the beach in Mykonos this weekend.

Two months after announcing the end of her relationship with Johnny Depp, French singer/actress Vanessa Paradis soaked her sexy bones in a black bikini while vacationing in Corsica the other day.

In June, Vanessa and Johnny split up after 14 years -- and having two children -- together.

You'd think Kate Upton could NEVER walk down the street without being noticed -- but she actually did a pretty bang-up job of hiding her curves in NYC. Damn sports bras!

The 42-year-old "Magic Mike" hunk was joined on vacation by his gorgeous pregnant bikini-clad wife Camila Alves.

The sexy couple look belly happy to be expecting their third child.
