Sylvester Stallone's daughters post envy-worthy swimsuit photos from family vacation

Sylvester Stallone's family is soaking up the sun.

The actor is dad to three daughters: Sophia, 22, Sistine, 21, and Scarlet, 17. The ladies, along with several cousins and other family members, jetted off on an enviable vacation to Croatia, and each photo is more gorgeous than the next.

"Mi familia," Sophia, who graduated from the University of Southern California in May, captioned one of the snaps.

A photo posted by one of their cousins shows the whole clan together on a boat. It's unclear whether Sly himself joined in on the European vacation.

The "Rocky" star never hesitates to gush about his children on Instagram, regularly posting sweet family photos and videos. He recently shared a video of himself, his wife and Sistine and Sophia dancing along to a car tune.

Earlier this year, he marked daughter Sistine's birthday with a glowing message: "This is such a wonderful day! It's our remarkable SISTINE's 21st birthday!" he wrote. "I couldn't be prouder to be such a lucky parent of such an extraordinary young lady!"
