The actress and her musician husband seemed to have joined Reba McEntire's Pray For Peace campaign which Nicole resolutely confirmed in the message that she shared with the video!
Here's what Nicole wrote on Facebook:
This is a puuuurfect family picture!
Sienna Miller was spotted in Santa Monica yesterday with her mom and baby Marlowe, and as they sauntered around the city, we got a glimpse of where all the good looks come from.
We don't know where the actress' mom has been hiding out, but she should come out more because we enjoy seeing the beautiful generations of the Millers!
