Sylvester Stallone isn't the only knockout in his family!

His gorgeous daughter Sistine has been named and It Girl on Town & Country's Annual "Modern Swans" List — and we couldn't be more proud of the 18-year-old on this amazing accomplishment!

This special list highlights the 50 "most stylish—and talked-about—young women" in showbiz. Sistine, along with Ella Richards and Princess Olympia of Greece, were featured on the magazine's latest cover.

Sistine — who just signed with IMG modeling agency — admitted she hopes to expand her career outside LA in the future. "I feel that a smart move would be for me to go to college in NYC and continue modeling there," the Rocky star's middle child told the news outlet. "But it all kind of depends on if I'm working, and what my parents think."
