In an Instagram post holding the baby, Payne said he was “very blessed” to be a father.
The couple has yet to settle on a name, he said.
“I’m incredibly happy to welcome our new baby boy into the world, it’s a moment that I will never forget for the rest of my life and my favourite memory I have so far,” said Payne, 24. “I’m completely in awe of his incredible mother and how she has been the whole way through this, she’s really made my dreams come true. We haven’t named him yet but he’s already capturing hearts including mine. I feel very blessed.”
Payne and Cole, 33, began dating last year, but met in 2008 when Cole, a former member of the pop group Girls Aloud, was a judge on the U.K. version of Simon Cowell‘s talent show, The X Factor. Payne was just 14 at the time.
He would later be paired with the four other members of One Direction who also appeared as contestants on the show.
