Just a little more than a week after sources confirmed to PEOPLE Johnny Depp popped the question to Amber Heard, the engaged couple were out Saturday night at a private charity event in Anaheim, Calif.
Dressed down in a white T-shirt and black skintight pants, the street savvy bride-to-be showed off one major accessory – her engagement bling.
With her hair loose around her shoulders, a glowing Heard was spotted supporting her main man while he hit the stage with Mike Campbell, Steven Tyler, Alice Cooper and Marilyn Manson at the rock show benefiting Servite.org, a non-profit charity.
Pals recently described Depp as "lovestruck" by his future wife.
"She's a great match for him and his individuality," a source told PEOPLE. "She's a free spirit."
