Los Angeles - Louis Tomlinson says fatherhood is "intense".
The 24-year-old singer attended the Brit Awards in London on Wednesday with his One Direction bandmate Liam Payne and revealed it was tough leaving his newborn son Freddie Reign behind in Los Angeles.
During an interview with Laura Whitmore for ITV2, he said: "Fatherhood is good. It's intense. It's really exciting. This is my first time away from Freddie so it's tough.
Band members Harry Styles and Niall Horan did not attend the awards ceremony at London's O2 and Louis joked that if they won an award, he would sell Harry and Niall's.
He quipped: "If we win who gets their awards, we could sell them."
Meanwhile, the pair have been keeping busy during One Direction's hiatus, with Liam saying: "We've been doing a bit of writing out in LA, it's been really fun. I've been in the studio, he's got different things on the horizon."
One Direction won the award for video of the year at 2016 Brit Awards.
