Sylvester Stallone and his brood were living it up on the French Riviera ... making everyone who's not there extremely jealous.
Sly, along with Jennifer Flavin and his 3 daughters Sistine, Sophia and Scarlet, were the picture of beauty on yacht. Kinda goes without saying the women gorgeous. That's 21-year-old Sophia is in the copper-colored metallic bikini ... as they say in the law -- res ipsa loquitur. Look it up.
Stallone just wrapped Creed II" ... and the buzz is good.
