Union J's JJ Hamblett is a daddy!
JJ's other half, model Caterina Lopez, gave birth to a boy at 9:30am this morning. The couple have called the little bundle of joy Princeton J. Alexander. Nice little nod to the band there...
Princeton weighed in at 6lb and both mother and baby are doing well.
And look! Look! Here's a picture of his teenie-tiny feet! JJ tweeted this super-cute photo, along with the announcement of the name of his son.
Breaking the happy news on Twitter earlier, JJ said:
Caterina went into labour on Wednesday night and JJ was tweeting his excitement throughout the night.
In earlier tweets, he said: "AND NOW WE WAIT!!! :-))))))) x"
"NOT LONG NOW!!!!!! Sooooooo excited :))))) xxx"
Even One Direction's Niall Horan was among the hundreds of well-wishers.
His message read: "Congrats JJ mate!"
Plus his bandmate George Shelley, who tweeted: "Congratulations JJ and Cat! New little one in the family now so proud of you both," George wrote. "I'm not the youngest member anymore!! Haha Love You!"
And Josh Cuthbert said: "SOOO HAPPY for JJ and Cat!! Its an amazing day and couldnt happen to 2 more amazing people. Chuffed to bits. The baby is gonna be beautiful."
