Robert Pattinson and Kristen Stewart have finally reunited after spending over two months apart. A source tells Us Weekly that Pattinson, 26, flew back to L.A. on March 16 after filming The Rover in Australia for the past couple months. Since his arrival back in the States, Pattinson has been staying with his 22-year-old girlfriend at her home. Proving their romance is still alive, the couple, however, were photographed by fans out together Tuesday, March 19 at karaoke bar. "I just ran into them at a karaoke bar by my house . . . mellow night," a fan tweeted with a picture. "They were just there hanging out with a few friends." In the picture, Stewart smiled and flashed a peace sign while Pattinson showed off his freshly shaved head. While her boyfriend was away filming, Stewart tried to keep herself busy by hanging out with her friends in L.A. The On the Road actress helped celebrate Twilight costar Taylor Lautner's 21st birthday in early February and visited the batting cages with him just last week.
