The Rock of Ages gang stuck together after their LA screening last night for an afterparty. Julianne Hough posed alongside her boyfriend, Ryan Seacrest, while her costar Alec Baldwin made the rounds with fiancée Hilaria Thomas. Tom Cruise didn't stay around after the credits rolled, but Malin Akerman and Russell Brand did. The Rock of Ages premiere brought out tons of other stars as well, including writer Justin Theroux, Josh Duhamel, and Zac Efron. The Adam Shankman-directed adaptation of the hit musical opens next Friday on June 15.
