After running errands on Saturday morning, a radiant Reese Witherspoon cheered on her son Deacon at his soccer game in Brentwood.

We still can't believe the Oscar winner gave birth to son Tennessee just one month ago! She looks amazing, and she hasn't let three children slow her down one bit! On Friday night Reese made her first post-baby red carpet appearance at the opening of the Rag & Bone store in West Hollywood, turning heads in a blue dress and black booties.

Fun fact: Reese's hubby Jim Toth wore a gray Rag & Bone suit for their 2011 wedding at her estate in Ojai, California.
