Who is the hottest Hollywood Rob?
The rumor mill can simmer down for a bit, because Celebuzz has the real story behind Robert Pattinsons casual conversation with a mystery brunette at the Sun Inn bar in London, England on Christmas Eve. 

A source tells Celebuzz that the female in question is actually RPattz’s best friend Tom Sturridge’s ex girlfriend. The breakup, however, didn’t cause a rift in the friendship circle and the girl is still good friends with both Rob and Tom. As of late, Tom is dating Sienna Miller — whose birthday is coincidentally today, Dec. 28. 

So where is the Twilight heartthrob off to next, and will he be kissing his girlfriend Kristen Stewart at midnight to ring in 2012?

Rob is heading back to Los Angeles where, according to our source, will meet up with KStew for New Year’s Eve. Despite reports to the contrary, they are said to be planning a low key evening together rather than an end of the year blow out party.

While her beau was in London for the holiday, Kristen spent her Christmas with her family and has been enjoying some low key night with her gal pals. Both actors need a well deserved vacation between the Breaking Dawn hoopla and Kristen shooting Snow White and the Huntsman.  

This isn’t the first time Rob’s friendships have been called into question. Earlier this month, RPattz, 25, and Disturbia actress Sarah Roemer, 27, hit up the quaint Hollywood hotspot La Poubelle with friends before making their way to the Soho House. The dinner was with a group of Hollywood producers and the two are just friends.

Do you think guys and gals can be just friends? Sound off in the comments!
