Linda Cardellini expecting her first child

Awww, little Lindsay Weir is all growed up.

Or, at least the actress who played her in the short-lived, but much-loved series "Freaks and Geeks" is. Linda Cardellini, 36, and boyfriend Steven Rodriguez are expecting their first child in early 2012, her rep tells People.

"They're excited to start a family together," says the rep.

Cardellini can currently be seen in the new movie "Return" opposite Michael Shannon. She plays a war veteran who has trouble adjusting to normal life. She also recently guest-starred on an episode of the new CBS series "Person of Interest."
