No, not that kind of birthday suit!
Dressed in a long gray trench coat tossed over a gauzy, lightly sequined white dress, the actress gave her typical lopsided little smile to photogs.
This is actually a much better outfit than some of her previous looks!
She accessorized with her fave Delvaux Madame black & red leather shoulder bag and black rag & bone boots.
Happy birthday, Katie, and many happy returns!
