Sara Gilbert and Linda Perry are expecting their first child together.

The 'Talk' co-host, who married the singer-songwriter in March, shocked her colleagues, Sharon Osbourne, Sheryl Underwood, Aisha Taylor and Julie Chen, by revealing she is pregnant on the show today (09.09.14).

The former 'Roseanne' actress, who already has son Levi, nine, and daughter Sawyer, seven, with ex-girlfriend Allison Adler, was supposed to face her fear of having a cinderblock broken over her stomach, as part of the show's Face Your Fears segment, but pulled out at the last minute, confessing: ''I actually can't do it, because... I'm pregnant.''

Her co-hosts immediately started jumping and cheering, suggesting this was the first time they had heard the news.

Sara then added that she had been ''really tired'' during her first trimester, but said that now: ''I feel good, I feel really good.''

The 39-year-old star started dating Linda in 2011 and they exchanged vows in a low-key ceremony in March in front of a small number of guests, including actress Juliette Lewis.

The former 4 Non Blondes singer, 49, who has penned hits for Christina Aguilera, Pink and Gwen Stefani, proposed during a romantic music-themed picnic in April 2012.

Sara previously said: ''I'm sitting there listening and I'm kind of daydreaming and I'm thinking like, 'If I ever proposed to her this would be an amazing way to do it.' The people picnicking next to us pull out string instruments from under the blanket, walk over and they start playing 'Love Song.'

''She goes to her backpack and she pulls out these T-shirts and the first T-Shirt says 'will' and then puts on another T-shirt and it says, 'you,' then 'marry,' 'me.' It was the most amazing proposal ever.''
