Willa will become a big sister in August, when Lauren is due to give birth to another daughter.

The actor and wife Anna Wood welcomed their first child, Bowie Rose, on April 2, and she wasted no time in making her social media debut.

Something tells us Lucille Ruby Odom will get to listen to the best lullabies around!

Presenting … the NBA's littlest baller! Oklahoma City Thunder star Westbrook has an MVP of his own: son Noah Russell, who was born on May 16. And considering he and wife Nina both played basketball at UCLA, we're sure it's only a matter of time before little Noah masters his jump shot.
