Vacations

The good times and tan lines continue in Hollywood with the hottest stars showing some serious cheek, and what better excuse to be a bum on a log than to browse through these bodacious babes flaunting their summer bums. All you gotta do is sit back, scroll and vote!

Kicking off the booty battle ... Em Rata is taking on Sydney Sweeney! It's a tough call as both gals are known for their curves, however only one of these ladies is takin' home the W!

No question Kendall Jenner and Alix Earle are always workin' their lil' hineys off -- so a summer vacay is necessary -- but which sexy celeb are you lookin' back at the hardest?!

Bradley Cooper and Gigi Hadid have serious skin in the game ... showing a lot of it on a yacht in the middle of the Mediterranean Sea.

The actor and his model girlfriend stripped down to a limited amount of swimwear for a sun-drenched day on the waters surrounding Sardinia, an island off the coast of Italy.

Bradley's catching Italian sun rays in some black board shorts ... and Gigi is working on her tan lines with a lavender bikini, while keeping her money maker in the shade courtesy of a matching bucket hat.

Love is in the air, with Margot Robbie and husband Tom Ackerley joining fellow A-listers Bradley Cooper and Gigi Hadid for a swanky date night in Italy.

The pregnant actress was practically glowing as she cozied up to her film producer husband while aboard a yacht in Sardinia ... an Italian island in the Mediterranean Sea.

Margot was unafraid to put her growing baby bump on full display ... wearing a chic black tube top and matching skirt -- covering up slightly with an oversized white button-down shirt.

Gigi Hadid and Bradley Cooper are living it up on a yacht off the coast of Italy ... and they're mixing romance with family time.

The actor and supermodel are floating around the Mediterranean on a big boat ... lathering each other up with sun tan oil and packing on the PDA with hugs and kisses.

Gigi and Bradley don't have the yacht all to themselves though ... his 7-year-old daughter Lea De Seine was onboard too ... Bradley co-parents her with Russian model Irina Shayk.

The three amigos shared a banana boat ride together, with Lea up front, Gigi in the middle and Bradley acting as the caboose.

Bradley soaked up the sun in some olive green swim trunks and Gigi showed off her runway-ready figure in a skimpy black and white bikini.

There were a few smooches and warm embraces on the deck ... but they didn't go full "Titanic."

The couple tooled around in a smaller boat too, and Gigi took a dip to cool off.

Gwyneth Paltrow is flaunting all the summer fun she had with her family -- and one of her famous best buds -- actress Reese Witherspoon.

Paltrow posted a carousel of photos on Instagram Reels, showing her amazing summer with her 2 kids -- Apple, 20, and Moses, 18 -- as she traveled all over the world, touching down in exotic locations.

The 3 are seen walking through the mountains, checking out tourist attractions and flying through the clouds. In the pics, Gwyneth and Company are swimming, paddle-boarding and enjoying artwork and some great food.

Salma Hayek is celebrating her timeless figure as she celebrates 58 trips around the sun ... marking her birthday with a bikini photo dump ... and all the shots are recent.

The actress proudly posted 18 photos of her in skimpy bikinis and revealing swimsuits on her 58th birthday Monday ... noting, "none of these are throwbacks."

Check out the gallery ... Salma's looking finer than ever here. She's like a fine wine, just getting better with age.
