Sienna Miller traded in London’s overcast winter weather for sunny Santa Monica by coming to the United States. She brought her adorable baby, Marlowe, with her. Sienna looks ready to take every opportunity to enjoy the sunshine, and I don’t blame her! Here she is on a walk with Marlowe. The woman carrying Marlowe isn’t identified, so I don’t know if she’s a nanny or a relative.

Regardless, I’m sure it’s good for Sienna to have help. Every working mother needs help! According to IMDb, Sienna’s currently filming ‘Foxcatcher.’ It looks like she’s still spending as much time with Marlowe as she can, however. At least they’re filming in a nice location.
