Santa came early this year for Reese Witherspoon and husband Jim Toth when their son Tennessee was born on September 27. On Friday, the actress was appropriately honored as a role-model mother at the March of Dimes' Celebration of Babies.

"It's always such an exciting time in your life when you have a brand-new baby," Witherspoon gushed. "It's Christmas and it's so nice to have this beautiful present in our lives."

Megan Fox quietly became a mom around the time that Witherspoon welcomed her third child, and she and husband Brian Austin Green had nothing but good things to say about March of Dimes.

"It's an amazing organization," said Green. "Anyone that supports and takes care of children and newborns and pregnant women -- you can't lose."

March of Dimes is a leading nonprofit organization for pregnancy and baby health.

Other notable attendees included Hilary Duff, Elizabeth Banks and the master of ceremonies Nick Cannon. Watch the video for more.
