Summer

If you've ever compared Kim Kardashian's ass to a flotation device, turns out she agreed with you ... because it's literally for sale now.

Kim released a bunch of new Kimoji merch on her site Tuesday -- and we noticed she's selling a pool floatie in the shape of her epic ass, which retails for a cool $98 ... plus $10 shipping.

The Butt Pool Float is currently available for pre-order, and will ship as early as June (kinda late, no?). There's not much of a description for the product either ... butt it pretty much speaks for itself.

It's big, and it floats. Sort of like this.

Gisele might have the greatest gig as a supermodel, but the guy in charge of prepping her ass for the camera has gotta be a close second.

Gisele squeezed in a very wet photo shoot in Rio on the heels of the Olympics. She's officially retired from runway modeling, but thank God she's still posing for pics like these.

We're guessing the butt wrangler does NOT get hazard pay -- shouldn't be paid at all, really.

Beyonce isn't even living life on the edge anymore ... she's going right over it!

We got these shots of Bey and Jay Z balling out off the coast of Sardinia on their rented super yacht, the Halo. Yes, the Halo. But instead of sunbathing or sipping bubbly ... Beyonce decided to go all daredevil and dive off the top deck.

Looks to be at least a 30-foot drop, and we think that's Jigga recording video from below. Maybe she was inspired by the Olympics ... or maybe she's making a quick escape.

Bottom line ... #CakesintheOcean

Orlando Bloom called dibs Saturday ... showing Sardinian sunbathers the girl was his.

Orlando and Katy Perry were all over each other on the Italian coast ... probably not even noticing they were the main attraction.

Miranda who?

Sasha Obama's summer job at a Martha's Vineyard restaurant is going to cramp her style in a big way, thanks to a slew of child labor laws.

We did some checking, and there are a bunch of things Massachusetts prohibits the president's 15-year-old daughter from doing at Nancy's Restaurant. Among them, she can't:

-- cook on an open flame

-- operate pressure cookers, broilers, food slicers, cutters or mixers

-- bake anything ... period

-- operate microwaves that heat above 140 degrees

-- transport grease hotter than 100 degrees

-- work in freezers or meat coolers

-- wash windows higher than 10 feet from ground level

And this is interesting. We've spoken with people who were at Nancy's when Sasha was there, and they say there was no visible evidence of security. We're told no one was searched and nothing seemed out of the ordinary.

Justin Bieber just broke his "no photos" rule in a big way ... letting an obscure rap duo shoot a rap video in his castle.

The Biebs recently ran into a guy named BB the Jerk, a member of the L.A. rap duo These White Kids. Turns out Justin's a big fan of the duo's YouTube videos. The next thing BB knew, he and his rap partner were partying at Bieber's pool party.

At the party BB casually mentioned he had a new song called "Michael Phelps" and Justin suggested they get a video camera on the spot and shoot the music video for the song.

The video features hot chicks, of course, Bieber jumping fully clothed into the pool and there's even a cameo with Brazilian superstar Neymar Jr.

Looks like the 2016 Rio Olympics may have a new anthem.

Dwyane Wade bolted Miami for Chicago ... but he's still kickin' it off the court with superstar ex-Heat teammate and BFF Chris Bosh ... bro-ing out at C.B.'s Malibu mansion.

The former teammates linked up in the 'Bu Wednesday for some quality man time ... gettin' in a bunch of activities, from jammin' out on the drums and guitar to hiking (while their wives tagged along and drank sangria).

If anyone thought there was a drop of bad blood between D. Wade and Bosh ... this video surely puts that to rest.

Britney Spears mixed business with pleasure this week flying to Hawaii on the heels of her new album announcement.

David Guetta's got major dirt on his GF, and she's got it on him too ... 'cause it's just what ya do in Ibiza.

The EDM superstar and Jessica Ledon went mudding on one of the islands near Ibiza ... just like Kate Hudson did a couple weeks ago.

No, Chrissy Teigen is not on vacation in Hawaii, but she's definitely hanging loose with John Legend ... and 3-month-old baby Luna.

The ridiculously gorgeous fam is chilling on a yacht off St. Tropez ... like a ton of other celebs this week. We're guessing Luna and John are big fans of mama Teigen's outfit.

Mom boobs -- they're not just for kids.

Kourtney Kardashian's got her brood a crazy Nantucket estate for July ... and Scott's there too!

Kourtney's rented out a 7 bedroom, 8 bath Cape Cod pad, and it's pretty spectacular. The pics were enticing enough for Scott to ask if he could tag along, and Kourt obliged.

The house goes for $6,600 a night, but we're told Airbnb hooked Kourtney up.

East Coast, beware ... you've been invaded.

It's been a year and half since Cristiano Ronaldo and bikini model Irina Shayk broke up -- but they're each doing okay ... with Shayk chillin' with Bradley Cooper in Italy and CR7 partying with Eva Longoria in Spain.

Irina and Bradley have been together since April 2015 -- though they haven't spoken publicly about their relationship.

Ronaldo, on the other hand, hasn't settled down at all -- and has been spotted out with all sorts of different ladies since the big split.

He's currently in Ibiza -- where he ran into Eva Longoria.

But the real love of Ronaldo's life ... himself ... the dude takes more selfies than Paris Hilton -- and recently busted out the selfie stick to get the perfect angle on his yacht.

Enjoy the eye candy.

Christina Milian's popping out of her swimsuit, in all the right places ... and we don't mean Ibiza.

The singer's doing a little vacay, and possibly a little shopping, for a swimsuit that will provide better boob coverage.

Lady Gaga looked surprisingly comfortable with a solid and snug wedgie as she lounged poolside in Cabo.

Brazilian model Adriana Lima's Greek vacation was like a mini Euro Cup of hotness with a lot of girl-on-girl action.

Lima turned up on the beaches of Mykonos vacationing alongside Polish football star Robert Lewandowski, his wife, Anna, and German baller Sami Khedira. Neither of their national teams made it to Sunday's Euro Cup final, but they're still winners judging by the photos.

The model who accused Chris Brown of assaulting her has surfaced again ... this time on the beaches of Miami with the bare minimum of clothing.

Liziane Gutierrez accused Brown of punching her earlier this year during a party in Las Vegas. No criminal charges were filed, though she's filed a lawsuit against him.
