Tom Cruise, Julianne Hough, and Diego Boneta posed together on the rock-and-roll-themed Rock of Ages red carpet in LA yesterday evening. While most big premieres happen midweek, this one was enough of a party to merit the Friday-night spot. The trio, with Julianne standing out in her bright yellow dress, were joined by other costars, including Russell Brand and Catherine Zeta-Jones. Josh Duhamel dressed the part in a long wig and no shirt with Fergie by his side, while Zac Efron kept it casual to check out the scene. Jennifer Aniston's boyfriend Justin Theroux wrote the screenplay for Rock of Ages, and he was looking dapper in a sleek suit, though he didn't have Jen on his arm for the arrivals. Aniston did look sexy in white for an event to honor Shirley MacLaine the night before. Also without a date was Tom Cruise, whose wife Katie Holmes is currently in Asia for her own work obligations.
