Actress Sara Gilbert has announced that she and her partner, songwriter Linda Perry are expecting a child.

Gilbert who appears on the sitcom ‘Big Bag Theory’ and the daytime chat show ‘The Talk’ revealed the news during an episode of the chat program.

Gilbert was challenged to lie on a bed of nails and have a cinder block broken on her stomach as part of the shows ‘Face Your Fears’ segment.

Gilbert declined the challenge, sharing with her colleagues that she was turning down the challenge not because she was afraid, but because she is pregnant.
