robert-pattinson-back-together-kristen-stewart-mystery-blond-sienna-miller-gi.jpg“Twilight” co-stars Kristen Stewart and Robert Pattinson have been rumored to be giving their relationship another go after a break this summer, but now People magazine is reporting that they are “officially a couple again.”

Sources tell the mag that Pattinson has also decided not to sell the Los Angeles home he and Stewart shared prior to their split. The couple broke up in July after Stewart was photographed kissing her married “Snow White and the Huntsman” director Rupert Sanders.

But even though these lovebirds are “officially” back together, they’re currently on opposite coasts with Pattinson in New York and Stewart in LA. While in NYC on Saturday (Oct. 6), Pattinson got the rumor mill churning by — gasp! — talking to another woman! He was photographed chatting up a “mystery blond,” but sources at the club say it was totally platonic.

“He stayed at Electric Room late,” a source tells Us Weekly, adding that he and the woman chatted “in a friendly way, nothing more. He kept to himself mostly.”  

“He was hanging out with some friends,” another source says, noting “there were girls and guys there.”

Among those girls and guys were Pattinson’s pal Tom Sturridge, his fiancee Sienna Miller and Michelle Trachtenberg. Based on the pics, some fans have surmised that the mystery woman might be Miller’s sister, Savannah.
