Blake Lively and Sister Robin in Beverly Hills Pictures

Blake Lively linked arms with her sister and a girlfriend on a casual stroll through Beverly Hills yesterday. The trio browsed among the exclusive boutiques on Rodeo Drive, then grabbed a bite to eat at the Cheesecake Factory. Blake and boyfriend Ryan Reynolds arrived on the West Coast over the weekend and since then they've been enjoying the nice weather. Ryan was even spotted taking a swim at the Beverly Hilton pool. Blake's California getaway comes just after filming for the final season of Gossip Girl began. Blake stepped out in a bright blue Marc by Marc Jacobs dress on set in NYC last week, though the final 13 episodes don't begin airing until October.
