Sienna Miller told UK’s Telegraph that she recalls a time when she and her Casanova  costar, the late Heath Ledger, went out one night with her mother while shooting in Venice.

“It had been pouring with rain and Heath ran out in the middle of St. Mark’s Square and we were running around, and I slipped over on my arse. He picked me up and everyone started laughing. We all ran back to his flat and he gave me these dry pajamas to get home in.”

The actress held on to them until last November, when Ledger visited her home one night.

“He was having trouble sleeping, I gave them back, to help him sleep. When he died, I was so sad that I didn’t have these stupid pajamas anymore, so his father found them to give to me.”

Miller has since brought the sleepwear with her to Prague, where she is currently working on the action flick G.I. Joe, along with a CD featuring the music of her friend Tarka Cordell, who also passed away earlier this year.
