Summer/Beach

Kim Kardashian slipped into a tiny bikini and hit the beach in Mexico ready to roll around in the sand ... with her kids.

Yeah, North and Saint are on vacay with mom. The whole fam went out Thursday for some fun in the sun -- and the kids are so freakin' adorable they almost upstaged Kim's famed assets.

Almost.

Kevin Hart and Eniko Parrish's Caribbean honeymoon is a bootyful thing to behold.

The newlyweds hit the beach in St. Barts after tying the knot this past weekend.

He's puffin' on a cigar, but let's be clear -- Eniko's ass is what's really smoking here. Kev gets the picture.

As if they need anything more -- the Harts also have kick-ass accommodations. They're staying at the world famous Eden Rock hotel, in their Villa Rockstar ... typically, nearly $23k per night this time of year.

Charlotte McKinney swaps beaches like she swaps boyfriends.

This time Santa Monica beachgoers got an eyeful.

The Carl's Jr. model used to be a Malibu regular, but that was when she was dating Stephen Dorff, who has a beach house there.

Kylie Jenner's birthday vacay continues to be the gift that keeps on giving ... to all of us.

KJ's still down in Turks and Caicos with Tyga and her squad. We're guessing she decided to celebrate that Tyga's a free man again by freeing something herself ... dat ass.

Kylie Jenner may be the birthday girl, but Tyga's the one who scored the best gift.

Kylie backed that big ol' butt up right into her BF's crotch during a beach outing in Turks and Caicos.

Kylie and Kendall Jenner paraded around Turks and Caicos in skimpy bikinis ... not that we're complaining.

Kylie celebrated her 19th birthday on the island and brought along her sister and some friends. Check out the pics ... oughta get you ready for thirsty Thursday.

Oh look ... there's Tyga!

The company that made floating around on huge birds a thing is calling fowl on Bloomingdale's for teaming up with a rival and ripping off their prized product ... its Giant Swan.

International Leisure Products -- creators of the inflatable Giant Swan seen in pools across America -- is suing Australian-based company Sunnylife for allegedly making and selling knockoffs of its bird ... according to court docs obtained by TMZ.

ILP claims Sunnylife is stealing their product's image through its own swan floatie and making stacks off it ... they also say Bloomingdale's is helping by housing the "Really Big Inflatable Swan" in one of its New York stores.

We have to say ... the similarity is pretty damning.

Now ILP wants the copycat pool toy yanked from shelves and even wants Sunnylife's customers to return any fake swans they bought ... oh, and they want money too.

Just goes to show ... there can only be one swan in the retail pond.

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

Rick Ross is going all out when it comes to big boss escapades, and parasailing is now officially off the checklist.

Yung Renzel got airborne Monday off a beach in southern France and even got video of his tandem flight.

Alessandra Ambrosio's on an endless yacht vacation that just gets better and better ... courtesy of her smoking hot friends, including Sofia Richie.

Lionel's model daughter is hanging with Alessandra and co. off the coast of Ibiza. They've been going cray cray on vacay -- holding hands leaping into the water, dancing with each other ... and showering on deck. Lots of showering.

Ariel Winter has a remedy for the SoCal heatwave -- just wear less.

Ariel was out and about in L.A. over the weekend wearing an outfit that's as cooling as the law will allow. Far as we know there are no plans for another 'Dukes of Hazzard' reboot.

But this pic might change some minds.

Former Victoria's Secret angel Doutzen Kroes joined the yacht party that could totally pass for a runway fashion show.

The Netherlands native hopped on the same yacht in St. Tropez where we've seen Alessandra Ambrosio, Joan Smalls, Lily Donaldson and Constance Jablonski ... soaking up the sun and getting very wet.

Eva Longoria got an eyeful of asses and boobs while committing a major faux pas.

The actress and hubby, Jose Baston, are on vacation in Ibiza and caught a free show on a nude beach. They did NOT join in the au naturel fun.

It's not often that supermodel Alessandra Ambrosio is just another chick in the crowd -- but it's also not often she's on a yacht packed with Victoria's Secret models. Yes, dreams do come true!

Joan Smalls, Lily Donaldson, Constance Jablonski -- who've all walked the VS runway -- were there too. So was Nicole Richie's little sister, Sofia.

Two Wilhelmina models got down and dirty ... which would explain the wet t-shirts.

Ashley Robbins and Nereyda Bird flaunted their stuff Tuesday during a Miami photo shoot.

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.
