This is Rumer Willis leaving a "Dancing With the Stars" rehearsal -- or more accurately ... it's Rumer's perfect ass leaving rehearsal.

On fleek ... comes to mind.

Rumer's already taken the MVA (most valuable asset) on this season of 'DWTS' -- and a lot of people who give a crap about that show ... think she's a lock to win the mirror ball thingy in the finale.

Don't all guys sit around the house like this???

Here's soccer superstar Cristiano Ronaldo ... striking a very spread eagle-ish pose to promote his new CR7 underwear line.

According to the press release, Ronaldo's new undies are supposed to be super soft thanks to "superfine microfiber" material.

Here's international supermodel Irina Shayk ... showing off her INSANE physique during a beach trip in Cancun, Mexico.

The 29-year-old's bikini top battled heroically to stay in position as Irina splashed around in the surf ... and while there were several close calls ... it ultimately emerged victorious.

Of course, Shayk recently broke things off with her longtime soccer superstar boyfriend Cristiano Ronaldo -- who's gotta be kicking himself right now ... or banging someone else.

Undefeated boxing champ Danny "Swift" Garcia will have a MAJOR advantage when he steps in the ring this weekend ... AN EXTRA TOE!!!

This video is awesome!!! Garcia was out in NYC -- where he's gearing up for his big PBC main event bout with Lamont Peterson on Saturday -- when he revealed Piggy #6 on his right foot.

"That's why I'm never off balance and I've never been down," Garcia says.

Danny says he used to be embarrassed about the toe situation when he was a kid -- but now, he's learned to LOVE his extra digit ... and says he's super proud of his bonus metatarsals.

We don't know what your diet will be like over the next month ... but Floyd Mayweather might be doing a little calorie counting, 'cause the champ has three lbs. to shed before the May 2 superfight.

TMZ Sports got their hands on a pic of Floyd tipping the scales for his mandatory 30 day weigh in ... and the Money Man came in at 150.5 ... 3.5 pounds over the welterweight limit of 147.

If you're worried about Mayweather making weight ... don't. We spoke with his high class chef not too long ago and she told us Floyd typically ratchets up his diet and training closer to fight date.

As for Manny, we're told the medical board of the WBC has been trying to reach out to the Filipino slugger for his weigh in ... but hasn't been able to make contact.

We saw him a little while ago ... at See's Candies.

The plus size beauties of Lane Bryant are dogging the more diminutive angels of Victoria's Secret -- and the clear winner is us! The battle's already plenty sexy, but it couldn't hurt to throw a Playboy chick in the mix.

Asking for a pillow fight would just be greedy, but ... fingers crossed!

Kate Upton says she was furious at the photographer who released the video that made her really, really famous ... but we don't believe her.

Kate says she had no idea Terry Richardson would post her "Cat Daddy" video telling Vogue UK, "I was like, that was disrespectful, you could have told me!"

She claims the video was shot for fun, and never thought it would be uploaded on YouTube for millions to enjoy.

Now here's the rub. At the beginning of the video, Terry does an intro, saying, "I'm Terry Richardson, and only in America, tonight ladies and gentlemen Kate Upton demonstrating the Cat Daddy. Take it away Kate."

Snoop Dogg 's wife is flashing her own skillz as a potential video vixen ... because Shante Broadus and Snoop's daughter Cori are twerking their asses off with L.A.'s best.

Despite reports of its death ... twerking is very much still a thing, and we got video of Snoop's ladies jumping on the bootywagon with premier ass-shaker, Lexy Panterra. Sources close to Lexy tell us Shante and Cori are burning calories with her every Monday.

Lexy's biz is taking off ... she even created a twerking app with singer Christina Milian -- which we're guessing is Lil' Wayne approved.

The Doggfather's so impressed, we're told he and Shante are flying Lexy to their home in Vegas for 2 weeks ... so they don't miss any classes.

We got Shante after class, and let's just say ... Snoop's gonna be a very happy man.

SPOILER ALERT: Ryan Reynolds looks badass as Deadpool and is set to make a ton of comic book nerds very excited.

Reynolds was on the Vancouver set of the upcoming Marvel movie wearing Deadpool's full regalia ... and looking spot on as the anti-hero. Just a guess based on the pics, but Ryan might want 'em to let out the inseam a little -- especially if the movie spawns sequels.

The movie is set for a 2016 release and will also feature Ed Skrein, Silicon Valley's TJ Miller and Gina Carano.

If you haven't seen the footage that was responsible for the whole project getting greenlit ... drop your swords and treat yourself right now.

Calvin Harris wasn't always the hot guy slaying the hottest girls ... it wasn't that long ago he was geeky, awkward, unkempt and in need of a shower.

Harris was photographed in Australia in 2008 ... way before he hit it big, buffed up big-time, and started dating the likes of Rita Ora and Taylor Swift.

Since then, he's cut and colored his hair, hit the gym, fixed his teeth and discovered the sun.

Oh yeah, and made millions and millions and millions of dollars.

Props to the Daily Mail for unearthing the epic pic.

Former "Charlie's Angels" star Jaclyn Smith may have hung up her gun garter but she's still smokin' ... at 69 years old!

Smith -- who will turn 70 in October -- was out shopping in Beverly Hills on Monday ... and it's obvious SoCal living has been VERY good to her.

Kylie Jenner let her fingers do some walking down her sister Kendall Jenner's shorts, and then -- because she's a giver -- posted it on social media for the world to see.

The Snapchat looks like it's behind the scenes of a photo shoot ... and shows the sisters doing a lot of sexually charged goofing around -- and then it gets all touchy feely.

Seems Richard Sherman's elbow's all better -- 'cause the guy was healthy enough to get on the 1s and 2s at a crazy pool party in Vegas this weekend ... with his pal Brody Jenner!

The two -- along with Richard's teammate Kam Chancellor -- took over the DJ booth at Tao Beach at the Venetian ... providing the beats as a bunch of young, hot, barely-dressed (mostly drunk) people partied their faces off.

Later that night, the gang took the party to Tao Nightclub ... where Jenner has a DJ residency.

We're told the guys were cool, took pics with tons of fans -- and gambled a little bit later that night.

Thanks to our friends at SpyOnVegas.com for the pics.

Check out 14 of Eastwood's sexiest shots -- but prepare for the urge to save a horse and ride a cowboy.

Among Jessica Alba's many talents ... one stands out above the rest -- looking hot in a bikini. Exhibit A: the pics from her latest trip to St. Barts.

And if you thought acting was Jessica's best talent -- you haven't seen her movies, and you definitely haven't seen these photos.

Jessica Alba continued to do what she does best Thursday in St. Barts ... rock a bikini better than pretty much anyone.
