Chelsea Clinton is making the most of Summer! On Saturday, the former first daughter slipped into a bikini for a boat day during her vacation near Sardinia, Italy. Chelsea was joined by her husband, investment banker Marc Mezvinsky, as well as fashion designer Diane von Furstenberg and her husband, Barry Diller.

She isn't the only former first daughter to give birth in the past year — Jenna Bush Hager welcomed a baby girl on Aug. 13.
