Sienna Miller remembers Casanova co-star Heath Ledger

"Heath and I had this amazing night out in Venice with my mother," Miller told Britain's Telegraph Magazine. "It had been pouring with rain. Heath ran out in the middle of St. Mark's square and we were running around, and I slipped over."

Miller continued, "We all ran back to his [apartment] and he gave me these dry pajamas to get home in," Miller said.

"When he came over to my house last November, and he was having trouble sleeping, I gave them back, to help him sleep," she said.

But after 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 revealed.
