Sienna Miller: Wet T-Shirt Contest!

Sienna Miller seems to have trouble with water while promoting her latest flick, G.I. Joe: The Rise Of Cobra.

On Thursday (July 23), the 27-year-old British actress and costars Rachel Nichols and Dennis Quaid got caught in the rain during a photocall on the roof of the Hotel de Rome in Berlin, Germany.

Yesterday, Sienna arrived by boat at the London photocall — with wet pants.

What water-y situation will Sienna get into next??
