She tried to blend into the massive crowd at Coachella this weekend, but Kristen Stewart's baseball hat actually gave her away.

The Twilight actress, who turned 22 on April 9, was spotted at the music festival rocking boyfriend Robert Pattinson's signature Baltimore Orioles cap with American Eagle maroon denim shorts, an aerie by American Eagle Concert Bra Corset and ripped gray tank on Saturday.

And while Pattinson, 25, didn't join his leading lady this weekend, the two are scheduled to be back in Vacouver for Breaking Dawn: Part 2 reshoots in the coming weeks.

The couple could also walk the red carpet together at the Cannes Film Festival next month where they both have new films -- On the Road for Stewart and Cosmopolis for Pattinson -- to promote.
