Robert Pattinson, Kristen Stewart Twilight Eclipse Hotel Cafe Bobby Long Marcus Foster

Last night Rob Pattinson and Kristen Stewart checked out friend Sam Bradley's concert at the Hotel Cafe in Hollywood, and we spotted the Eclipse stars sneaking out the back after the show. The normally poker faced K. Stew definitely had a hint of a smile on her pretty face, and Rob walked out in front shielding his lady from cameras and a handful of Twilovers who were going into freakout mode.

A source inside the venue tells X17online exclusively, "Rob and Kristen seem to be getting much more comfortable with their romance -- they definitely aren't shy about it at all these days." What's next, an official announcement that they're a couple? It's about time guys!
