24 star Mary Lynn Rajskub is pregnant with her first child. The comedienne, who plays Chloe in the hit drama series, and boyfriend Matthew Rolph, 27, are expecting the baby at the end of the summer (08). And Rajskub jokes the pregnancy was a result of the ongoing Hollywood writers' strikes. She tells People.com, "With the strike going on, I had to keep busy! We are thrilled and couldn't be more excited."
