Autumn Reeser of No Ordinary Family let it slip on Jimmy Kimmel Live last night that she’s expecting a mini-Autumn!

She told Jimmy:

“I’m pregnant,”

She pointed to an invisible baby bump and joked that the Kimmel interview would be how her husband — writer Jesse Warren — found out about the pregnancy.

If you don’t know Autumn, you should. She’s appeared on hit shows The O.C. and Entourage, as well as scantily-clad in Maxin.

Autumn, 30, and her husband wed in May of 2009 and will have a little one coming by May of 2011! Congrats to them.
