New Mom Sienna Miller: “My Brain Doesn’t Work”

Actress Sienna Miller is experiencing a phenomenon many new moms know well: Baby brain!

“She’s sleeping upstairs,” Sienna said of her almost 1-month-old daughter Marlowe during a telephone interview this week. “I’m good though my brain doesn’t work.”

Despite being busy with her baby girl, Sienna is already making time for work as well, calling into HBO’s Summer Television Critics Association panel in Beverly Hills yesterday to promote her new film The Girl.

Baby Marlowe is the first child for the 30-year-old actress and her fiance Tom Sturridge.
