Zac Efron fit in some exercise in Beverly Hills yesterday. He showed off his biceps in a tight shirt and followed up his workout with a coffee stop. The actor is back on the West Coast after making an appearance at Calvin Klein's runway show during New York Fashion Week. He was home again on the West Coast in time to attend the debut of the Rock of Ages musical in LA on Tuesday along with several other celebs. Zac was solo at the gym and during his night out at the theater, despite a recent report linking him to I Am Number Four star and ex-girlfriend of Russell Brand, Teresa Palmer.
