Report: Robert Pattinson and Kristen Stewart Spent Last Night Together!

Robert Pattinson and Kristen Stewart spent the night together, in the same room, at the Chateau Marmont in Los Angeles last night, according to a report.

A Radar Online spy claims to have verified this, spotting Robsten and an unidentified English guy entering suite 79 of the famous hotel Thursday evening.

Around 8:45 p.m., a guitar was delivered to their room. Rob opened the door and the spy slipped in to say hi. Rob said: "OK, thank you." The spy then left.

Around 1:30 a.m. this morning, the English dude (not Rob, his friend) left the hotel suite. Rob and Kristen did not leave the room ... ALL NIGHT LONG!

Long rumored to be obsessed with each other, might a steamy romance finally be in the cards for Robert Pattinson and Kristen Stewart? Looks like it could be ...
