    Amber Heard is one beautiful bride-to-be!

    Johnny Depps fiancée was practically glowing as she watched her future hubby perform at a private charity event at Servite High School in Anaheim, Calif., on Sunday, Jan. 27. And if the 27-year-old actress' smile wasn't bright enough for you, that massive engagement ring is pretty darn blinding all by itself.

    Heard and Depp, 50, haven't officially spoken out about their plans to say "I do," but sources (along with that bling!) confirmed to E! News earlier this month the famously private pair was planning to wed.

    We're told that Heard was joined by a bodyguard as she watched her fiancé perform from backstage. Depp's appearance was a surprise—and obviously a welcome one—on a bill that also included Alice Cooper, Marilyn Manson and Steven Tyler.

    Depp and Heard, who showed off her ring to a few people around her, looked cheerful and really seemed to be enjoying themselves. While onstage, a witness said, Depp would sneak a glance back at Heard every now and then and blow a kiss.

    They stayed at the event for about two hours.

    When the future spouses first met while filming The Rum Diary in 2010, they were both romantically involved with other people. Depp was still dating longtime girlfriend Vanessa Paradis (the mother of his kids, Lily Rose and Jack) and Heard was in a relationship with photographer Tasya van Ree.

    At the time, Heard told Guest of a Guest working with the star was "everything you'd hope working with Johnny Depp would be."

    "He's absolutely amazing, as far as his talent and him as a person," she gushed.

    Aww! Well, in 2012, the Rum Diary costars had split from their respective partners and quietly began to date. Depp even bought Heard a horse (of course)! They didn't make their red carpet debut as a couple, however, an art gala in L.A. held earlier this month.

    This will be the first marriage for Heard and second for Depp, who was married to makeup artist Lori Anne Allison from 1983 to 1985.
