Summer/Beach

Kim and Kourtney served up a treat for 2-for-1 Kardashian sisters in bikinis ... and Kim's ass is back to hogging the spotlight.

The Kardashians were down in Mexico this weekend with their gal pals -- including Brittny Gastineau, Malika Haqq and Larsa Pippen -- hitting the beach in some pretty revealing swimwear.

Kim's bikinis definitely took the cake ... and provided plenty too for the paps. Kourtney, meanwhile, seemed more focused on flashing some serious underboob.

Just a healthy reminder ... summer is coming.

Eva Longoria does the opposite of take it easy on a Hawaiian vacation ... she prefers screaming "Geronimo" from the highest cliff!!!

Eva's on vacation, island hopping with hubby Jose Baston, where she was very clearly in full activity mode ... jumping in waterfalls in Oahu one day, then jumping on a paddleboard in Maui on another.

She did sneak in a kiss or 2 along the way, but you can tell paddling was still at the forefront of her mind.

Miles Teller and longtime GF, Keleigh Sperry, didn't have to worry about sinking or swimming as they hit the surf in Hawaii like a normal couple enjoying a romantic vacation.

The two coasted on a pair of floaties Monday in the blue Pacific ... not that they needed them because the water looked pretty shallow. Only thing missing -- a cold one in their hands.

Madonna's daughter, Lourdes Leon, gave new meaning to the phrase ... suns out, buns out when she hit South Beach ... with her appetite.

Madge's 20-year-old not-so-baby girl slipped into a bikini -- showing off what her mama gave her -- and also made sure to take a food break.

Lourdes absolutely inhaled a sandwich out on the beach. See, don't worry Mom ... she's eating.

And looking very healthy.

Devon Windsor is a beauty by the sea ... and her boyfriend knows it.

Paps got the Victoria's Secret model Saturday in Miami with her BF, Johnny Dex, where the couple got frisky in the water.

Neil Patrick Harris and husband David Burtka have chillin' in the heat down pat.

Add Teyana Taylor to the list of smokin' hot women to peel on that classic red swimsuit -- but her version shows way more ass-ets than Pam's ever did.

Teyana was part of a "Baywatch" themed photo shoot down in Miami, and went with red hair to complement the swimwear. Between TT, Ashley Graham and Niki Taylor -- who still looks phenomenal -- who gets to be C.J. Parker?

They should wrestle for it.

Jessie James Decker needs the best lighting possible to show off her awesome body in a bikini -- and while in Miami ... she got it.

Eric Decker's smokin' hot wife hit Miami beach Tuesday for a photo shoot, where 1 of the lighting guys had to use a white bounce board on her for top-notch illumination.

Yeah, it's still technically winter ... but it's beach season for Katherine Webb.

Mrs. AJ McCarron hit the beach in Alabama with her baby son, Raymond -- and while he's cute and all ... Katherine kinda stole the show.

As for AJ, there are talks he could be traded during the off-season. Based on these pics, we're hoping he lands in a place with a beach.

"Orange Is the New Black" star Jackie Cruz ain't spending her time off from the show locked up inside somewhere.

Jackie, who plays Flaca, hit Miami Beach Sunday in a drastically different uniform than the prison onesie people are used to seeing her wear on 'OITNB.'

Scott Disick treated himself like the lord he is when he escaped from the Kardashians ... by dropping tens of thousands to chill for a few nights.

Scott was hanging at the Setai Hotel in Miami Sunday through Tuesday night, and we've learned he stayed in their Grand Suite. The name makes sense -- it has 3 bedrooms, spa/sauna, gourmet kitchen and a swagged out TV room ... plus killer ocean views. Before ya book, it goes for $12,500 per night.

We're told he ordered plenty of room service while partying with his many lady friends and one guy friend you probably know -- Don Julio. 1942 to be exact.

As we reported, Scott beelined it for South Beach after a blowout with Kris Jenner and Kim Kardashian in Costa Rica. The Lord spares no expense when bouncing back.

Anthony Kiedis isn't the same guy after a round of surfing ... he literally changes right in front of you.

The Red Hot Chili Peppers lead singer hit up Malibu Saturday to catch some waves, and then stripped down to his birthday suit for a discreet wardrobe change in the open.

Alessandra Ambrosio's soaking up summer in Brazil ... or at least her buns are.

The VS supermodel's purple bikini did its best to hang on in the surf of the resort town Florianópolis.

Alessandra Ambrosio's gonna pass on the eggnog by the fireplace, and opt instead for sipping straight from coconuts, while chilling in a bikini. Who says supermodels ain't smart?

The VS Angel is down in her native Brazil, soaking up the summer weather. She's also making Christmas much merrier for the rest of us.

Nicole Kidman and Keith Urban might have a white Christmas, but it damn sure won't be sunburned.

Nicole and her country star hubby are down in Sydney (where it's summer) for the holidays, and on Monday they hit the beach. Keith was shirtless and all about catching a tan.

Nicole, on the other hand, was protecting her fair complexion at all costs.

Hugh Jackman's mouth says he's hanging up his Wolverine claws, but his ripped beach body says otherwise.

Hugh took a dip down in Australia, where someone tried to show him up by flashing even more skin ... downstairs, anyway.

Smuggling. It's not just for drug dealers anymore.
