Sienna Miller apparently has spent a night partying with Robert Pattinson. The actress, who stars as The Baroness in "G.I. Joe: Rise of Cobra", was caught on camera rushing out of the "Twilight Saga" heartthrob's hotel in London at 3.15 A.M. on Wednesday, May 4, and got into an awaiting car to be driven back home.
Despite the sighting, Sienna was not having an affair with Rob. Hours earlier on Tuesday night, May 3, the 29-year-old beauty joined the "Bel Ami" actor and his best friend Tom Sturridge, who is rumored to be her boyfriend, at the Home House Private Members Club for a private after-party following the London premiere of "Water for Elephants".
Sienna has split from her on-and-off boyfriend Jude Law in earlier this February. She has since been linked romantically to the "On the Road" actor Tom. The two were most recently spotted meeting up at Japanese restaurant Sake No Hana in London in late April. Before that, they were spotted grabbing coffee and spending time together at The Dorchester Hotel.
The "Factory Girl" actress, who will next be seen in "New Year's Eve", has been kept busy lately with the London production of "Flare Path" at the Theatre Royal Haymarket.
