Robert Pattinson and Kristen Stewart Spent Last Night Together

Major Robsten update!

Radar Online reports that Twilight co-stars and rumored lovebirds Robert Pattinson and Kristen Stewart spent Thursday night together—in the same room!—at the Chateau Marmont!

According to a witness, R-Pattz and Kristen showed up with another male Brit at the fabled hotel in the evening, and a guitar was delivered to their room shortly thereafter, at approximately 8:45. (Presumably, Pattinson was in a jamming mood, as is often his wont.)

But the evening apparently wasn’t all music-making; the eyewitness says that the other male left the suite at about 1:30 a.m, leaving the rumored couple to enjoy some alone time.

Of course, they probably just spent the early-morning hours reading poetry to each other, right?

While the rest of the Eclipse cast is up in Vancouver preparing for filming, Pattinson and Stewart have apparently hung back in Los Angeles to meet up with their castmates on Sunday for the Teen Choice Awards—and apparently carve out a healthy chunk of alone time.

Tell us in the comments section: Is there any doubt left at all that Robsten is totally, blissfully on?
