Robert Patinson and Kristen Stewart are known for two things, starring in the immensely popular Twilight franchise and carrying on a secret off-screen romance. The pair, who star in the fifth installment of the franchise, Breaking Dawn: Part 2, have been dating since early 2009. Their every move has been documented and critiqued by the media and widely discussed by fans. They met during a 2008 audition for the first Twilight film. Pattinson has said that he became interested in being a part of the teen vampire saga when he learned that Stewart had been cast. In a Berlin press interview he revealed:

I'm a big fan of Kristen and I was before [Twilight]. In an interview with OK!, he went as far as saying he only auditioned for the film because of K-Stew:

The only reason I went to the audition was to see Kristen because I'd just seen Into the Wild. The 2007 film featured Stewart as a sultry guitar playing teen, who is desperate for affection.

Stewart and Pattinson will star in a combined six films this year including Snow White and the Huntsman, On the Road, and Cosmopolis. ,

Over the years, Robsten has been snapped at a number of events together. In honor of their three-year anniversary, here are a few fun and cutesy photos!
