Sienna Miller: Back to London Town!

Sienna Miller is all smiles as she arrives at Heathrow Airport on Thursday (November 11) in London, England.

The 28-year-old actress, who returned from a trip to Los Angeles, was on the same flight back into town as director Ridley Scott!

Earlier this month, Sienna had only wonderful things to say about her dear friend and Factory Girl director George Hickenlooper, who died after a heart attack at the age of 47.

FYI: Sienna is wearing the Express shawl collar sweater.
