Carson Daly has welcomed his third child.

'The Voice' host's fiancée Siri Pinter gave birth to a baby girl named London Rose on Wednesday (20.08.14) and the new tot weighed 8lbs 11oz.

Baby London joins the couple's two other children, Jackson, five, and 22-month-old Etta.

According to America's 'TODAY' show, Carson said: ''Siri is a warrior and I'm so amazed by her poise, grace and strength during this miraculous process.

''Watching Jack and Etta meet their new sister was like watching a scene in a movie, directed by God.''

Siri was due to give birth to their new baby on Saturday but ended up going into labour days later.

Carson recalled: ''It's incredible. We thought this was going to happen on Saturday and it didn't. We went home. It was a long couple days of waiting.

''Finally, yesterday, I got a call ... It was Siri saying 'Come on, come on! It's happening right now!' and like out of a movie, I sped to the hospital and they were literally waiting for me to get there and we had our beautiful baby girl.''
