Former Girls Aloud band member Kimberley Walsh, who earlier this week let the cat out of the bag about Cheryl's pregnancy, has welcomed her second child with her husband Justin Scott.
The singer took to Twitter to announced the happy news about the birth of her son on Wednesday, posting: "We have another beautiful baby boy couldn't be happier."

Their newborn son joins their first child, 2-year-old Bobby, who they welcomed in 2014.
The couple have been together for 14 years and married in Barbados earlier this year.
Five days ago, the singer shared a photo of her on Instagram sporting a large baby bump saying she was "getting excited to meet this little one!"
This week, Walsh appeared to confirm the world's worst kept secret, that her former Girls Aloud bandmate Cheryl is pregnant.
She told Closer magazine: "I'm just happy that she's happy. And she'll be a brilliant mum. She has loads of nieces and nephews, so she's used to the madness of children."
Kimberley added: "Both she and Nicola [Roberts] are naturally good with kids.
"I think they've both always planned to settle down and have a family."
