It's Mary Lynn Rajskub's first child

Mary Lynn Rajskub, who plays the quirky computer genius on "24," has good news to handle this time.

The actress is pregnant with her live-in boyfriend Matthew Rolph's baby, reports People.

"With the strike going on, I had to keep busy," says Rajskub. "We are thrilled and couldn't be more excited."

Rajskub, 36, and Rolph, a 27-year-old personal trainer, are expecting the child at the end of summer.

Rajskub is known for playing the wry Chloe O'Brian on FOX's "24." Her other credits include "Little Miss Sunshine," "Legally Blonde 2," "Punch-Drunk Love" and "Dude, Where's My Car?"
