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??

Sienna Miller arrives to the launch of G.I Joe: The Rise of Cobra via inflatable boat held at London’s HMS Belfast on Wednesday (July 22).

Looks like Sienna rode a little too close to the edge of the boat — the backside of her pants were soaking wet!

Also pictured: G.I. Joe stars Dennis Quaid, Channing Tatum, Karolina Kurkova, Rachel Nichols, Marlon Wayans and Adewale Akinnuoye-Agbaje. G.I. Joe is out in theaters on Friday, August 7.

FYI: Rachel is wearing a symmetrical Brian Reyes shift dress.
