Rochelle Humes has warned parents to ''lock up'' their daughters following the birth of Frankie Sandford's baby boy.

The Saturdays singer and her soccer player fiancé Wayne Bridge welcomed their first child Parker into the world this morning (18.10.13), and her bandmate - who has five-month-old daughter Alaia-Mai with husband Marvin Humes - has joked the tiny tot's good looks will break hearts when he's older.

Taking to Twitter, Rochelle wrote: ''Massive congrats to @frankiethesats and Wayney! The best text to wake up to this morning ... lock up your daughters Parker Bridge has arrived (sic)''.

Una Healey couldn't wait to share the exciting news that Parker weighs exactly the same as what her 19-month-old daughter Aoife Belle - who she had with husband Ben Foden - weighed when she was born.

Una tweeted: ''Huge congratulations to @FrankieTheSats and Wayne on the the birth of their darling baby boy Parker, so so excited to meet him! X

''AND he was born the exact same weight as Aoife Belle! 7lb 13oz! aw (sic)''

Frankie - who is also joined in the girl group by Mollie King and Vanessa White - announced the birth of her son on Twitter earlier today and assured fans mother and baby are ''doing well'' and she is ''absolutely besotted'' with her new arrival.
