Amber Heard looked like one proud fiancée when she attended one of Johnny Depp [1]'s shows in Anaheim, CA, over the weekend. Johnny took to the stage at Servite Catholic High School for a special charity concert that included appearances by Marilyn Manson, Alice Cooper, and Steven Tyler. Amber, wearing a StyleMint t-shirt, stood just off the stage from Johnny, where she flashed her massive engagement ring while recording her beau's performance on her iPhone. During Johnny's performance, Amber chatted with a friend and Marilyn, who has been friends with Johnny since he was a teenager. The two have even worked together on a music project, having recorded a cover of "You're So Vain" for Marilyn's 2012 album, Born Villain.

News broke earlier this month that Johnny and Amber are engaged [2]. The notoriously private couple has been dating since 2012, but they only recently started to go more public with their love as they posed for photos together at a pre-Golden Globes party in LA [3]. According to a source, the two have been engaged for some time now, but Amber only recently started to wear her ring.
