5 After Midnight (previously 5AM)'s Kieran Alleyne has become a dad.
The singer announced the news on Twitter that his ex-girlfriend had given birth.
He told fans simply: "Well damn….. I’m a dad.”
Fans and fellow stars of The X Factor were quick to offer congratulations, with Four Of Diamonds' singer Caroline tweeting: "Woohoo😍😍❤ congratulations guys so happy for you!! Xx"
It was revealed during last year's series that the former couple were expecting.
According to tabloid reports at the time, Kieran and his bandmates Nathan Lewis and Jordan Lee held a meeting with mentor Louis Walsh after the unexpected news.
An insider told The Sun newspaper: “It’s a whole different game now that Kieran knows he’ll soon have a family to support.
“This news has just given him and the lads even more drive to win the The X Factor.”
The boys didn't quite manage to triumph but did make the final and have since been signed by Simon Cowell's Syco record label.
But unfortunately last month Kieran revealed the relationship with his girlfriend was over.
“No matter what our relationship status may be, I still consider [her] to be my best friend," Kieran told The Sun newspaper. “I know she will be the most amazing mother to our son. I’m looking forward to us starting a new chapter together as great friends and committed parents to our baby boy.
“We are both incredibly excited to welcome him into the world together.”
A spokeswoman for the group commented: “We can confirm Kieran and [his girlfriend] are no longer together. They remain close friends.”
