Miller says she treasures Ledger's PJs

London -- British actress Sienna Miller said a pair of pajamas Heath Ledger once gave her helps her stay connected to the late Australian actor.

Miller and Ledger co-starred in the 2005 period romance "Casanova."

Ledger died in January at the age of 28 of an accidental lethal combination of prescription drugs.

"Heath and I had this amazing night out in Venice with my mother," People.com said 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. We all ran back to his (apartment) and he gave me these dry pajamas to get home in."

Miller said she returned the blue-checked sleepwear to Ledger two years later when he complained he was having trouble sleeping.

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