Summer/Beach

2:36 PM PT -- Kobe has ... (ahem) ... weighed in on the pics -- saying, "Objects on camera may appear larger than they do in the mirror haha."

He added, "ok...ok...ok. Gimme 30 days #challengeaccepted #mambathick #mambabeast."

Kobe Bryant's chest is just like his jumper ... SMOOTH!

The Mamba ditched the shirt for a relaxing poolside session in Portofino, Italy while on vacation with his family -- but just like the rest of us, he couldn't muster up the strength to put his phone away.

Italy is like a second home for Kobe -- he grew up there while his father played pro ball in Calabria and speaks fluent Italian.

Portofino is poppin' right now for rich people -- Kris Jenner hit up the vacation spot last month. Same with Tiffany Trump. And Heidi Klum was there last week!

Maybe they all use the same waxer?

It's 89 degrees in Miami ... which means MORE HOT CHICKS IN BIKINIS!

Here's Camille Kostek -- ex-New England Patriots cheerleader and possible Rob Gronkowski GF -- struttin' around the beach in a butt baring bikini.

Kostek is currently vying for a coveted spot in the upcoming Sports Illustrated Swimsuit Edition and seems to be a front-runner ... at least, judging by the positive response on social media.

It's clear Camille's feeling herself these days -- check out the bathroom video she posted.

Swag.

"Catfish" star Nev Schulman got wet and wild after his wedding ... in a reception that ditched the banquet hall dance floor for riding waves at the beach.

Nev married his longtime girlfriend, Laura Perlongo, in his father's backyard in East Hampton, NY Saturday -- their 9-month old daughter Cleo was the flower girl -- then took the party of about 100 guests to the ocean.

The kick ass reception featured beach cabanas, a DJ, pizza, beer and glasses of rosé. Nev's 'Catfish' co-star Max Joseph was on hand and gave a speech about the newlyweds ... then took an inflatable flamingo for a ride.

Mazel!

Rachel McCord might not be as famous as her sexy celebrity sister, but she sure looks like a star.

The model and younger sister of "Nip/Tuck" and "90210" actress AnnaLynne McCord hit up the beach in Santa Monica this week ... and had herself a fun and sand-filled photo shoot.

After applying sunscreen to her buns, Rachel enjoyed a smoothie, read a magazine, snapped a few selfies, took a dip and even fed some birds.

Former Miss USA Olivia Jordan and model Allie Ayers partnered up in Miami Beach ... in pastel swimsuits incredibly easy on the eyes.

The bubbly blondes teamed up for a Sports Illustrated photo shoot during Miami Swim Week ... and they definitely work well together. Allie opted for a 1-piece instead of a bikini ... but still managed to reveal more than Olivia.

Jordan was crowned Miss USA in 2015 and went on to place second runner-up in Miss Universe. Allie's one of 15 finalists in S.I. Swimsuit's open casting competition.

Always good to lean on friends ... especially half naked ones.

Jessica Alba's now tanning for 2 ... and has no problem flaunting it either.

The actress put her baby bump on full display as she lounged at the beach in Hawaii Tuesday. Alba's on a babymoon getaway after announcing Monday she's expecting her third child with husband, Cash Warren.

Although she's a mom these days, and expecting another, ya can't see Jessica sunbathing without reminiscing about her most famous beach pose ... from more than a decade ago.

It really is like a fine wine.

Eva Longoria and her husband's honeymoon phase still seems to be in full swing after more than a year of marriage -- boobs in the face will do that!

Eva and her media mogul hubby, Jose Baston, hit the beach in Marbella, Spain Tuesday ... and he had a particularly nice view as she helped him up from the water.

The couple tied the knot in May 2016 and show no signs of slowing down with the fun activities.

Now this is effective marriage counseling.

Kimberley Garner is hotter than the Saint-Tropez sun ... point blank, period.

The 27-year-old former "Made in Chelsea" star looked amazing as she meandered on the beach in Pampelonne, then hopped on a speedboat.

Kimberley's branched out ... she's now a swimwear designer.

She's also super smart ... she saves money on hiring a model; because clearly no one can do it better than her, right?

Christina Milian and Karrueche Tran are a little late to get on the "hot babes eating burgers" train ... but that doesn't mean we don't appreciate the effort.

Christina and Karrueche got their bikinis on and hit the beach Tuesday in Miami, where at first they got all wet ... and then dried off and chowed down on some cow.

Their burger bikini fest wasn't for any type of Carl's Jr. commercial -- in fact, the company ditched that whole concept earlier this year ... sad as it may be.

Still ... it's good to see an homage here to the good ol' days -- intended or not.

Don't bother them, they're eating.

Hilary Duff has a new young dude in her life, and he's already getting very familiar with her bikini bod.

Hilary was with the mystery man over the weekend on a Malibu beach. Don't know how long they've been together, but they weren't shy about getting physical in the water. Besides a makeout sesh ... they also did some surfing.

She's definitely got his back.

Looks like Hil's moved on from celeb trainer Jason Walsh, who she was dating this past Fall.

Kendall Jenner doesn't need a bathing suit to go swimming at the beach ... her see-through dress will do just fine.

Kendall was at a beach party with Bella Hadid Sunday on the Greek island of Mykonos, where she decided to take a dip in a transparent black dress ... champagne bottle in hand and all.

Kendall and Bella have been on a bit of a Eurotrip of sorts ... bouncing around from Paris to London for Pride, and now Greece in a matter of about a week.

As for the wardrobe malfunction here, she clearly doesn't seem to mind how tightly the wet dress clings to her body -- and, frankly, neither do we.

The real question: who's the dude flinging her around? Better call A$AP.

Lionel Messi's having a great week -- like super duper great -- and the celebration's continuing for him on his honeymoon in the Caribbean.

Messi and his new wife, Antonella Roccuzzo, hit up the beach with their 2 sons for some fun in the sun ... and an epic game of Smashball!!!

If it looks like the soccer star doesn't have a care in the world, it's probably because he signed a massive contract with FC Barcelona -- $33.6 million a year through 2021 -- just days after tying the knot with his childhood sweetheart.

Oh and by the way ... she looks smoking hot.

Cristiano Ronaldo can move like nobody else on the pitch ... but still has some work to do before he looks as graceful on water.

The famous soccer star showed off his flyboarding skills in the sea near Ibiza ... but had to take a dive when the jet pack didn't go the way he expected. All good, though ... he could just regroup on his mega yacht.

Ronaldo's in Spain with his gf Georgina Rodriguez, who had some fun on a jet ski herself.

Jen Selter is a true patriot when it comes to 4th of July -- just check out her red, white and blue thong and bikini ... and don't forget her ass.

The famous fitness model hit the beach for the holiday weekend, and even under gloomy skies ... she still sizzled next to the ol' American flag. A banging bod will do that sometimes.

Gillian Anderson's got another partner opening her files these days ... and sorry, Mulder, these 'X-Files' are strictly boyfriend privileges.

Scully and her bf, Peter Morgan, got steamy sitting poolside in Portofino. She showed off her hard bod in a blue bikini ... which Peter seemed to be fully enjoying. Smart and lucky man.

48-year-old Gillian's moved on from her 'X-Files' days, and now stars on the Starz series "American Gods."

They might wanna rework that title ... "American Goddess" feels a little more appropriate.

Liziane Gutierrez took advantage of the warm Memorial Day holiday weekend to do what so many other women in Miami do -- show off her ass.

The Brazilian model soaked up the sun and hit the water in Miami beach Sunday in a barely there white one-piece swimsuit. She also hopped on a jet ski ... but strictly for selfie purposes.

Liziane's booty might look familiar. As we reported ... she dropped $25,000 to go under the knife a few months back to get an ass like Kim K.

Money well spent?
