Watch Miley Cyrus, Alicia Keys Photobomb 'Voice' Fans

Hosts prank unsuspecting fans who won VIP experience at show taping

Alicia Keys and Miley Cyrus photobombed unsuspecting fans who stopped by the set of 'The Voice' for a photo opp.

Alicia Keys and Miley Cyrus surprised fans who visited The Voice set for a photo opp, for a good cause. The hosts photobombed for Omaze's latest charity campaign, where fans of the singing competition can donate at least $10 in support of charitable organizations while entering for a chance to win the VIP access at a taping of the show.

In the clip, Keys and Cyrus are lurking on set, which sees several superfans getting a tour of the set and posing for photos in the iconic chairs where the coaches sit. The photographer asked many of the fans about their favorite coaches, and the fans offered their reasons why Keys and Cyrus were huge inspirations to them. At one point, one girl ran screaming from her chair after being shocked by Keys standing behind her friend. "I mean, I freaked out when I met Alicia, so I get it," Cyrus said.

The donations go towards causes close to both Cyrus and Keys' hearts, the Happy Hippie Foundation and the We Are Here Movement. The contest will remain open until November 29th and will be won by a single fan who can bring a guest with them to attend the show and meet all the coaches.
