Jennifer Garner picked up a drink near the Pacific Palisades neighborhood and headed to a hair salon in West Hollywood yesterday. She's back in LA after a trip to Puerto Rico to visit Ben Affleck on the set of Runner, Runner. Jennifer, Ben, and their kids hit the beach for a fun family day during the vacation, though Ben was soon spotted back in front of the cameras with costar Justin Timberlake. While Ben works on his latest project, Jennifer is gearing up to promote The Odd Life of Timothy Green. She'll do press for the film over the weekend and continue making rounds throughout the month, even after the movie hits theaters on Aug. 15.
