Sara Gilbert has given birth to a baby boy.

The 40-year-old presenter - who already has son Levi, nine, and daughter Sawyer, seven, with ex-girlfriend Allison Adler - and wife Linda Perry welcomed son Rhodes Emilio Gilbert Perry into the world on Saturday (28.02.15) and the 40-year-old star revealed her happy news on her show 'The Talk' yesterday (02.03.15).

She also shared a photo of the little boy sleeping while wrapped in a blanket and a hat.

'Talk' co-hosts Julie Chen and Sharon Osbourne later sent congratulations to the couple via twitter.

Sharon tweeted: ''Congratulations @THEsaragilbert & @RealLindaPerry on the birth of your beautiful boy, Rhodes. I hope he has a healthy and spectacular life.(sic)''

Julie wrote: ''@THEsaragilbert and her new baby boy ... so happy for you and @RealLindaPerry! (sic)''

Sara announced she was pregnant on 'The Talk' last September, stunning colleagues Sharon, Sheryl Underwood, Aisha Taylor and Julie with the news.

The former 'Roseanne' actress 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.''

Sara started dating Linda in 2011 and they exchanged vows in a low-key ceremony last 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.
