Summer

Blake Lively's getting by with some help from her friend Taylor Swift, who's hosting a celeb-packed weekend celebration for Blake's 37th birthday at her Rhode Island seaside mansion.

TMZ got the first shots of Taylor and her man Travis Kelce chilling at the $17 million pad on Saturday. It looked like a romantic weekend getaway for them but turns out they were also prepping for their big-name guests to arrive.

Later in the day, birthday girl Blake showed up with hubby Ryan Reynolds -- and the couple shared a smooch outside on one of the home's many sun-kissed decks.

Y'all ready to hop on the PJ and hit Summer's hottest spot with the stars?! With all the hype and hoopla surrounding Italy, you could pretty much hear a pin drop in Hollywood, so come join big celebs like Kylie Jenner and Latto livin' the high life: fleeing L.A. and Rome-ing around Italy!

It appears these famous peeps -- like Alix Earle who stunned a high wasted stripey suit in Sorento -- were all about shedding layers and enjoying the coastal towns and beautiful blue waters of the Mediterranean.

Alex Rodriguez threw a solid shredded shot up on the 'gram while yachting around in celebration of his 49th birthday, and Heather Graham followed (swim)suit -- sharing a red-hot bikini shot from Liguria along the Italian Riviera.

Kylie Jenner is reminding you summer isn't quite over, posing for a series of spicy pics ahead of what she calls ... her "sexiest" swimwear ever!

The reality TV star revealed new swimsuit shots Monday and Tuesday for her upcoming Khy satin swimwear line -- and this campaign's way different from pushing lip kits.

Check out the pics ..KJ's poolside rocking a turquoise string bikini, and in another, she's lounging in front of a palm tree wearing a silver monokini -- both pics showing off her fit physique.

Robert De Niro's still looking like a raging bull as he celebrates another birthday ... taking a wild leap off a yacht while partying with his family!

His daughter Drena De Niro was recording when her pop took the dive for his 81st birthday, and let's just say his form was not Olympic in its nature.

Bobby D looked like he was lining up a standing pencil dive off the side of the boat, but midway he rolls over onto his side ... and ends up doing a full body flop into the blue waters. Drena, his oldest child, was immediately shocked and concerned.

Exotic vibes only!!! And, these luscious ladies are bringin' it -- clawing their way to your feeds in the sexiest of animal print swimwear! With different takes and variations of Summer's popular suit, ya better not mess with these strong and powerful gals!

Comin' in hot, Heidi Klum bared it all in a revealing cheetah print suit, Ashley Graham's spots never change donning a sexy leopard top, and if there's one thing Stassie Karanikolaou knows: it's pairing her striking angles with a smokin' hot two-piece!

Mariah Carey's heating up the Amalfi Coast, because even the Queen of Christmas needs a summer break ... and she's taking hers in a skintight pink swimsuit.

The singer-songwriter hit the waters on the famed Italian coastline Wednesday ... donning a pink and black spandex suit with a plunging neckline that revealed her black bikini underneath.

Mimi hopped on a boat with her 13-year-old twins -- Moroccan and Monroe -- lounging around as they soaked up the European sun, and Monroe threw her arm around Mom.

Grab your noodle, and float into your feels, because it's Relaxation Day! Yes the stars know how to party hardy but they take R&R to a whole 'nother level ... and today's not about skincare or hittin' the gym ... Today's task at hand requires nothing but floating in the pool!
