4. Kim Zolciak

The 39-year-old Don't Be Tardy star might love taking bikini-clad pics more than the selfie queen herself, Kim Kardashian West!

Needless to say, the trip was filled with swimsuit selfies.

The 42-year-old actress had lots of fun in the sun while vacationing in Spain with husband José Bastón in July. Longoria was seen confidently strutting her stuff in an array of string bikinis while packing on the PDA with her beau. 

The Desperate Housewives star even took to Instagram to defend her beach bod. "There's a lot of paparazzi in the beach today, you guys," she said. "If there are some unflattering bikini photos of me, I don’t care. I've been eating so much."

6. Ashley Graham

The 29-year-old supermodel has made a career out of showing off her curves in stylish, sexy swimsuits. 

Graham recently spoke with ET about the trials she faced regarding her size when coming up in the modeling industry. "Everything was about exterior, everything was about weight for me," she recalled. "I really had to step back and say, 'OK, am I looking for love through sex? Am I looking for love through food? Am I looking for love through the affirmation of fashion people who don't understand my body?' I had to really have, like, a come to Jesus moment."

In one pic of her playing on the beach, Michele captioned the season perfectly, writing: "I never want this vacation to end."
