The 24-year-old singer attended the Brit Awards in London with his One Direction bandmate Liam Payne and revealed it was tough leaving his newborn son Freddie Reign behind in Los Angeles, reported Female First.
"[Fatherhood] is good. It's intense. It's really exciting. This is my first time away from Freddie so it's tough," he said.
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.
