Carson Daly has become a father for the third time.

The 'Voice USA' host's fiancée Siri Pinter gave birth to a baby girl yesterday (20.08.14) and the couple have named their new daughter - a sister for Jackson, five, and Etta, 22 months - London Rose.

According to TV Show 'Today', the new arrival measured 22 inches long and weighed 8lb 11oz.

The 41-year-old presenter praised his ''warrior'' fiancee for her calm nature during labour.

He 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.''

Just last week, Siri - who got engaged to Carson last October - joked she was so overdue that strangers were ''frightened'' of her in case she suddenly gave birth.

She tweeted: ''It's pretty amusing how frightened strangers are of me right now. Especially when I scream QUICK CATCH THE BABY!! #10monthspregnant.(sic)''

Carson had previously vowed not to ''miss a minute'' of Siri's labour, no matter how busy he was.

He said: ''My family's the most important thing. I'm not missing a minute of the birth of my kid. Family first.''
