Carey Mulligan dating Robert Pattinson’s BFF?

Carey Mulligan is reportedly dating Robert Pattinson’s BFF! The British actress — who recently split from boyfriend Shia LaBeouf — is believed to have hooked up with hunky British actor Tom Sturridge.

The new couple have been spotted leaving Hollywood’s Chateau Marmont together and have been seen at the Hollywood Best Western, where Mulligan has been staying since her split from her Wall Street 2 costar LaBeouf.

“Carey and Shia had been really distant for a while,” a source said, “so it’s not really a big deal that she’s with Tom.

“Things were really bad with Shia toward the end, so it’s great that she’s happy.”

Carey and Tom were introduced by by mutual pal Keira Knightley, the source says, and they “clicked right away!”
