As Usmagazine.com reported in April, Jennifer Aniston, 38, has signed on as the new spokeswoman for smartwater. The former Friends star and yoga enthusiast is making signature smartwater bottles that will be in stores this July, and will appear in an upcoming campaign shot by famed photographer Mario Testino. The partnership marks the actress' first U.S. endorsement, although she has lent her famous face overseas to brands like Heineken, L'Oreal and Damiani jewelry.“We were thrilled that Jennifer discovered smartwater and realized what a difference it makes to her healthy lifestyle,” said Rohan Oza, smartwater’s senior vice president of marketing. “To us, Jennifer truly embodies what smartwater is all about as she combines substance and style like nobody else.”
