Ronda Rousey spent more time throwing punches on the set of her Sports Illustrated Swimsuit Edition modeling shoot ... than she did during UFC 184 ... and now there's video of the scantily clad workout.

SI just released the video ... in which Rousey says she was WAY more comfortable doing martial arts poses during the shoot than the traditional kissy-face looks.

Hey Rory ... you seein' this?

Check out these pics of tennis superstar Caroline Wozniacki -- featured in her very own spread in the Sports Illustrated Swimsuit Edition.

It seems Wozniacki's really let loose since golfer Rory McIlroy broke off their engagement last year -- she's been on several girls-only trips with her BFF Serena Williams ... and started posting all sorts of hot bikini selfies.

And now she's upped her game in the new SI pics ... even showing off her ass.

Caroline isn't the only athlete in the mag -- UFC badass Ronda Rousey also got a spread.

Stay tuned for those, but in the meantime ...

If there's one thing the Internet knows ... it's that Kate Upton in a bikini (and sometimes out of it) is an easy win -- and the folks at Sports Illustrated just rung up another W.

Kate's been getting a ton of attention for her "Game of War" commercials, which seemingly runs during every commercial break of sporting events.

So, S.I. just wanted to remind everyone they have the hottest Upton footage on the planet ... by posting a throwback video to a 2012 photoshoot.

Thank you, S.I.

Alex Morgan ain't the only chick on the U.S. National Soccer Team with a super hot body ... and Sydney Leroux is making sure Sports Illustrated knows it!!

Leroux -- who was part of the 2012 gold-medal winning Olympic team -- has been on a bikini photo posting tear ever since S.I. started to push the new Swimsuit Edition, featuring Morgan.

The pics ... they're good.

To be fair, Leroux's physique hasn't been totally ignored by the media ... she WAS featured in a semi-nude pic in ESPN's 2013 "Body Issue."

And get this ... there were rumors Sydney was dating 49ers QB Colin Kaepernick -- but neither side ever confirmed.

Too bad ... for him.

"Sports Illustrated" swimsuit model Chrissy Teigen isn't the selfish type -- telling TMZ, she doesn't care if her husband John Legend ogles at other hot women ... in fact, she loves it.

28-year-old Chrissy was out signing copies of the new "SI" swimsuit issue last night when we asked what she'd think if she caught John looking at the other ladies in the magazine.

Not only did Chrissy say she'd be into it ... she tells us, "We're pretty open to that kind of thing."

Danica Patrick's nipple is officially off the Internet ... TMZ Sports has learned the people at Sports Illustrated have finally removed a pic of the driver's exposed breast from its swimsuit website.

As we previously reported, several pics from a 2008 photo shoot were recently put on S.I.'s Swim Daily website as part of a "Throwback Thursday" gallery. One of the pics was a topless "selfie" in which Danica's nipple was fully visible.

There were questions as to whether the pic was posted by accident or if it was an intentional "artsy" thing -- but now that it's been removed from the gallery, it seems pretty clear ... it was never supposed to be there in the first place.

So ... Danica Patrick's exposed nipple is hanging out on a Sports Illustrated website.

The racy pic of the NASCAR driver is featured in a "Throwback Thursday" photo gallery on S.I.'s "Swim Daily" website ... which features a "selfie" style photo shoot of Danica from 2008.

We called S.I. to find out if it was a mistake ... or one of those intentional "nipples are artsy" sort of things ... but so far, we haven't heard back.

Terrell Suggs found out keeping eye contact with a smoking hot Sports Illustrated swimsuit model is way tougher than winning a Super Bowl -- even with a theater full of people watching.

It all went down during an S.I. award show celebrating 50 years of hot chicks ... when the Baltimore Ravens stud DE was presenting an award with Jessica Gomes.

To be fair ... T-Sizzle performed the full body eye exam as part of a corny, scripted award show joke -- but watch the clip ... he clearly enjoyed the view. Or he's a really good actor.

Sports Illustrated supermodel Chrissy Teigen just posed for a topless photo shoot with her fiance John Legend ... and now one of the topless pics has surfaced on the web.

But Chrissy ain't mad ... in fact, the person who posted the pic is the photographer -- and right after it hit Tumblr, Chrissy retweeted it and joked, "I figure you can't be suspended from a retweet."

The photo appears to be a frame from John's music video for his song, "All Of Me."

As of 8:11 AM PT, the photo is still up on Instagram ... but if you wanna see it, you better act fast -- we're guessing it won't be up long.

So, here's a photo of supermodel Bar Refaeli kissing another woman ... you're welcome.

The other chick appears to be Bar's good friend Orna Elovitch. We don't really know much about her ... but she got to go mouth-to-mouth with Bar, so she's clearly important.

Stuff like this almost makes you forget Bar tongue wrestled with the GoDaddy guy ... ALMOST.

It was a battle of the super babes as Sports Illustrated cover girl Kate Upton and A.J. McCarron's overnight sensation GF Katherine Webb -- who also appears in the S.I. swimsuit issue -- brought their gorgeousness to David Letterman in NYC on Monday.

Question is ...

Kate Upton's breasts -- and their owner -- are on the cover of the Sports Illustrated Swimsuit Edition for the second time ... proving good awesome things really do come in pairs.

Memba when TMZ published those pics of Kate Upton in a really tiny bikini in the middle of Antarctica??? Turns out we TOTALLY SCOOPED the Sports Illustrated Swimsuit Edition's cover!!!!!

Ooops!!!

Earlier today, the super-secret cover was leaked to the Internet ... featuring Kate in the middle of the frozen antarctic tundra ... a shoot they TRIED to keep under wraps.

We published the pics back in December, right around the time they were shot -- when the temp dipped down to 35 BELOW.

But Kate braved the elements like a stud -- and it totally paid off.

And now we have another reason to look at our candid shots from the glacial "set" ... as if we really needed one.

Bar Refaeli's mouth has the power to turn a regular man into a bona fide Casanova ... 'cause that geek she sucked face with in the Go Daddy commercial says chicks have been all over his jock ever since the spot aired.

The lucky sonofabitch in the commercial is Jesse Heiman who tells TMZ his life has completely changed in the past week ... and obviously, all for the better.

"I’ve actually had guys tweet me that they wish they were me, and girls tweet me saying they wish they were Bar.”

But the interest from the ladies isn't just from the cyber variety -- Jesse explains, "I have girls run up to me and take pictures with me, tweet me for dates.”

Jesse tells us his career has also exploded ... saying, "There are lots of inquiries coming in to my agent and manager, their phone has been ringing off the hook, but they are really letting me enjoy the moment right now.”

Kate Upton and Lindsay Lohan have something in common ... because Kate's assets were FROZEN recently -- when the curvaceous 20-year-old model stripped down to her skivvies for an Antarctica photo shoot ... where the temperature hit 35 BELOW!!!

We're told Upton and a camera crew boarded a private 10-day cruise from Argentina to Antarctica for a super-secret Sports Illustrated cover shoot. The cruise departed November 29th and returned December 9th.

The photos were shot both on the cruise -- with massive icebergs as a backdrop -- as well as on the penguin-filled islands off the coast of the frozen continent.

But don't worry -- we're told Upton only stripped to a bikini for a few minutes at a time ... and was otherwise wrapped in a pimpalicious fur coat.

As for the giant Oreo man -- 2012 marks the 100th year since the inception of the tastiest cookie in the universe ... and for some reason, this guy felt like celebrating.
