Sienna Miller recently opened up about the loss of her friend and Casanova costar Heath Ledger.

"Heath and I had this amazing night out in Venice with my mother. 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," Sienna recalled.

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

Sienna returned the PJs to Heath when he stayed at her house last November because he was having trouble sleeping and she thought it would help.

After Heath died of "acute intoxication," Sienna really wanted the pajamas back. Heath's father found them and gave them to her.

I would imagine this is something Michelle Williams wouldn't want to hear, but the idea of wearing a guys pajamas does sound rather endearing. There's just something about comfy men's clothes that goes straight to a woman's heart.
