Hot Bodies

Yep ... that's YouTube star Rebecca Black, best known for her 2011 earworm, "Friday" ... and we have a feeling these photos will be just as catchy for her fans.

Rebecca hit the pool at the Dream Hollywood hotel over the weekend. Apparently, she doesn't ONLY get down on Fridays. She's looking a helluva lot more grown up than the teenager most remember singing that annoying (we say that lovingly) one-off hit.

Y'know you done messed up, right, Scott Disick?

Sofia Richie was filling up Sunday in Bev Hills ... while rocking a midriff-baring top, sure to remind her Scott what he's abs-olutely missing out on these days. Photogs asked her if they've actually broken up, but 19-year-old Sofia was tight-lipped.

As we told you, Scott was all over some chick at Kanye West's album release party last week, and was overheard telling people he's single.

To each his own, but ... damn.

Bella Hadid's lunch runs are more fun than yours ... probably a lot sexier, too.

The supermodel was grabbing food to-go with friends in NYC Saturday when her boob nearly fell out the bottom of her crop top. It's hot in the city, so Bella's tiny shirt makes sense ... though her underboob appears to just be a happy accident.

Either way, Bella laughed it off and fixed the wardrobe malfunction on the run.

Betcha wish you were that bottle of Fireball whiskey right now.

WWE superstar Lana was spotted shakin' it on a balcony in Miami on Thursday afternoon ... picking up right where Nikki Bella left off with a bikini-clad day of fun in the sun.

All the Divas -- including Paige, Nia Jax and Brie -- are in South Beach shooting new episodes of their "Total Divas" tv show ... and they've been providing nothing but great content so far.

No John Cena? No problem ...

Nikki Bella returned to the set of "Total Divas" this week -- killin' it in a bright blue bikini ... and thank God, there are pics!

Nikki joined up with other WWE superstars including Paige, Lana and Nia Jax -- each looking insanely good in their bikinis.

The entire gang is in Miami for the show -- which just got renewed for 2 more seasons.

Bella's storyline this season should be the most interesting ... considering she broke off her engagement with John Cena, who's been publicly begging for her to take him back.

As we previously reported, the two are definitely still talking and it looks like Cena is making some headway ... but right now, they're still officially broken up.

Fitness model Jen Selter has taken her divine derriere to Greece where she posed up in a tiny bikini -- and, praise the booty gods, TMZ Sports has the pics.

Selter has been traveling all over the world lately -- modeling, working out and taking in the sights ... but she found some time in Mykonos to enjoy the beach in a crystal-studded thong bikini.

Fun Fact: there are 4 nude beaches on the island.

Not Fun Fact: Jen Selter didn't go to any of those.

Kourtney Kardashian and Kendall Jenner stuck to their guns on Memorial Day -- which, as far as we can tell, reads something like ... wetter is better.

The sisters posed for a photo together Monday, which showed them, Jordyn Woods and one of the Simi and Haze twins in their bathing suits ... and holding Super Soakers.

They definitely looked like a hot new posse of 4, rivaling some classic ones like the 'A-Team,' the 'SATC' gang ... or, hell, even the 'Golden Girls.' And then, suddenly, there were two -- namely, Kourt and Kendall striking floatie poses in the pool. Rear to rear, mind you.

You can hear Jenna Dewan saying it in this pic -- ain't no rings on this hand!!!

Jenna and Channing Tatum announced their split less than 2 months ago, but based on the smoking hot, body-hugging dress and swagger she was rocking Tuesday afternoon in Hollywood -- she won't be single much longer.

Jenna was stuntin' on 'em on her way into 'Jimmy Kimmel Live,' and ain't much more to say here ... except, maybe, damn.

Kim Kardashian's baring it all for her new fragrance line ... but it looks like she missed a spot this time while strategically covering her lady bits.

Kim posted another very risque pic Tuesday to promote her perfume -- KKW BODY -- and got creative with a new close-up angle from the front. Only issue is ... a little nip can be seen, which might not fly with Instagram's no-nudity policy.

So, enjoy it while you can.

As you may recall ... these nude shots have been part of the marketing campaign for her fragrance from the jump -- the last one featured even more vagina.

Cristiano Ronaldo's got a big game coming up this weekend ... and the soccer god's preparing for it by enjoying a big serving of cake at the beach ... courtesy of his bikini-clad baby mama!!

The Real Madrid superstar and Georgina Rodriguez were spotted catchin' rays in Ibiza last week ... showing the forward lookin' carefree leading up to the Champions League Final against Liverpool on Saturday.

While the other kids didn't appear to make it on the trip, CR7's oldest son, Cristiano Jr., was in on the fun ... getting thrown into the water by his dad.

Liam Hemsworth gets his good looks and physique from his mama ... and his daddy, clearly!

The youngest Hemsworth bro was out hiking Wednesday with his parents -- looks like they were in the Malibu Hills -- and even though he lovingly referred to them as "oldies" ... their bods are totally camera-ready.

This pic bodes well for Chris and Liam's futures -- their dad, Craig, is completely yoked, and mom Leonie looks like she's ready to run a marathon. Even the family dogs look fit!

Kristin Cavallari has returned to Mexico ... she's back on the beach -- only this time, she left her NFL hubby at home.

The former 'Hills' star grabbed a bunch of her girlfriends and jetted over to Tulum ... where they've been soaking in the sun and drinking wine on the sand. Good times.

Kristin even posted a bikini pic captioned, "Bummin' around."

Funny, considering the last time Kristin was in Mexico she convinced Jay Cutler to go full naked on the beach and posted a bare ass photo of the QB for all the world to see.

In fact, it appears the Cutler butt pic was shot at the same resort where KC's staying now.

As for Jay, someone's gotta stay home with the kids ... and since he doesn't have a job at the moment, might as well be him.

Models Abigail Ratchford and Gemma Lee Farrell didn't need any help oiling up on the beach in Miami ... they had each other to do the job.

The two hit the sand again Tuesday in Miami and were a bit more covered up than last time. When we say a bit ... we mean this time there were no nipple sightings.

Doesn't seem like Gemma missed a spot on Abigail, although they should seriously consider a stronger SPF. Unclear who the third wheel is, but she fits in nicely.

Here's Draya Michele setting the Miami pool scene on fire at Shore Club ... with a bikini that looks like it was made from the things the Ultimate Warrior used to tie to his arms.

Don't get it twisted, we're not complaining ... not even a little bit.

CAN YOU FEEL THE POWER?!

Of course, Draya is a swimsuit tycoon, who runs the Mint Swim bikini company ... and also happens to be dating Washington Redskins star Orlando Scandrick.

No signs of Scandrick in Miami though ... he spent the weekend in Los Angeles running a high school passing league tournament.

Jada Pinkett Smith's mother might be 64, but damn anybody who disagrees that her body screams BODY GOALS!!!

Adrienne Banfield-Jones posted this pic Monday showing off her washboard abs in a pink, multi-colored bikini. Adrienne -- who stars on Jada's Facebook Watch talk show, "Red Table Talks" -- captioned the Instagram pic, "64 and what? That part!!"

She got tons of praise after posting the pic and the sheer image alone inspired one particular woman who wrote back, "I’m 38 and I used to get scared of hitting forty. I used to get worried that by the time I hit 40’s I won’t be as desirable or hot or that I won’t be able to find love in my life because I’ve prioritized other things in life over love life. All of my worries just seem so ridiculous now."

Adrienne for the win!!

Kendall Jenner went from being barely covered in a bathing suit earlier in the day to practically naked walking a red carpet at Cannes.

Kendall required a mandatory double take in her sheer dress at the Chopard Secret Night party ... she arrived with very little support underneath. All she's wearing under her dress is a pair of nude underwear. They're hard to see but they're there.

Fact is, camera flashes have been known to expose a boob or two underneath sheer dresses ... and Cannes is known for being flash-heavy.

Still ... it appears Kendall knew exactly what she was doing, even if she played dumb on her Instagram.
