Rochelle Humes' baby is ''absolutely beautiful''.

The Saturdays star gave birth to daughter Alaia-Mai Humes - her first child with JLS singer Marvin Humes - on Monday (20.05.13) and bandmate Una Healy has revealed the couple's new arrival takes after her stunning mother.

Speaking to BANG Showbiz at the European premiere of 'The Hangover Part III' in London's Leicester Square on Wednesday (22.05.13), she gushed: ''We got to visit her baby, Alaia. She is absolutely beautiful.''

As the first member of the chart-topping girl group to have a child - 14-month-old Aoife Belle with her rugby star husband Ben Foden - Una, 31, is naturally a source of helpful tips for Rochelle, 24, and newly expectant mum Frankie Sandford, 23, but she worries the trio's constant baby talk is ''boring'' for fellow bandmates Mollie King, 25, and Vanessa White, 23.

Una added: ''I give all the advice I can, but I have to be careful because it can sound so boring to someone that might not have kids. So we have to be careful. We can't help it! We all talk about babies all the time.''

Meanwhile, in her first public comments since giving birth, new mum Rochelle took to Twitter to thank fans for their well wishes earlier today (23.05.13) and revealed that little Alaia-Mai has already developed a strong bond with her father.

She tweeted: ''Thanks so much for all of your lovely messages. I feel so so blessed. Alaia-Mai is just a little angel. We're all very happy. Thanks again x

''Marvin is a great daddy. Absolutely in love with his princess. Definitely a daddy's girl situation already started. So beautiful x (sic)''
