Rochelle Humes has given birth to a baby girl.

The Saturdays singer and her husband Marvin Humes welcomed their second child into the world on Friday (10.03.17) and have named her Valentina Raine Humes.

The brunette beauty took to her Instagram account shortly after the birth to share a sweet photograph of her holding her newborn swaddled in a white blanket.

She accompanied the shot with the caption: ''Our world is now complete. Valentina Raine Humes - Happy birthday little ones...'' followed by a pink heart bow emoji.

Marvin also took to his social networking sites to post the same picture and praise his ''beautiful'' wife on giving him an ''incredible blessing'' in the shape of another daughter.

Former JLS star Marvin said: ''Couldn't be a happier or prouder man, what another incredible blessing! My beautiful wife gave birth to our 2nd girl Valentina Raine Humes x (sic)''

The couple - who got married in 2012 following two years of dating - already have three-year-old daughter Alaia-Mai together and were initially worried that their little one wouldn't take to having a new baby sibling around as she's always had their sole attention.

Speaking to BANG Showbiz prior to the birth, the 31-year-old radio DJ said: ''Laia is so excited for a sibling, she was at the baby shower - she's so excited for mummy. She's desperate for a sister. She hasn't clocked yet that if it's a boy she'll forever be daddy's little princess. But at the moment she's all about girl power. But everything's girls girls girls. She's keen for a little sister.''

And, although the happy couple feel complete with their new addition, Marvin recently admitted that he hasn't ruled out the possibility of adding to their brood in the future.

He said: ''I mean I'd never say never to more kids. But we'll see.''
