Kimberley Walsh has said she is feeling slightly "shell-shocked" after the birth of her first child.
The former Girls Aloud star and her partner Justin Scott welcomed baby Bobby last week.
Writing in her OK! magazine column, she said: "A lot of people thought I was having a girl, so it was a nice surprise to have a boy.
"My friends had joked that my baby would arrive on time because I'm so punctual, and he did!
"I went into labour last Wednesday September 3 and gave birth at 4.52pm the next day - September 4 - which was my due date."
She said Justin was by her side during the birth and that she can't stop gazing at the new addition to the family.
"Like most new mums, I feel a bit shell-shocked," Kimberley told the mag, adding: "But Justin's being an amazing support and fortunately feeding is going well so far."
