The supermodel, hubby John Legend and baby Luna are in Venice, Italy for a little family vacay. Chrissy showed off her best assets in her loose tropical-themed outfit that perfectly matched her hair wrap.

Chrissy's diggin' her outfit and John's also clearly loving it ... he had to snap a pic.

Chrissy's cleavage is no stranger to stealing the spotlight ... who can forget the couple's "Slow Dance" mishap that left everyone wanting more?
