The One Direction hunk is enjoying being a father to baby Freddie Reign - who was born last month - and can already seeing himself expanding his family in future.

Asked how he is finding fatherhood, he said: "It's great, I'm enjoying it a lot and I'd definitely like more kids but not just yet."

Though little Freddie's first words are some way off, the 24-year-old singer - who is co-parenting the baby with his former lover Briana Jungwirth - already knows what he wants to hear first.

Asked what he hopes the tot's first word will be, he said: "It's a tough question because the immaturity is just pushing through there... but 'dad'!"

And the 'Drag Me Down' hitmaker is a hands-on dad who has no problem getting to grips with stinky nappies.

He said: "Have I changed a nappy? I'd actually probably changed about a hundred nappies before Freddie because I used to help out with my sister so I have changed his nappy, thank you!"

This week's BRIT Awards in London marked the first time Louis had been away from his Los Angeles-based little boy and he admitted he was missing his son.

Speaking to Capital FM at the MasterCard-sponsored event, he said: "I'm still getting used to it. It's my first time away from him so I miss him, obviously, but it's cool. I do get Father's Day now."
