Speaking to ITV2, the One Direction star couldn't help but gush over his newborn, saying: "[Fatherhood] is good. It's intense. It's really exciting."
However Louis confessed that he's finding it "tough" being back in London whilst Freddie Reign stays in Los Angeles with his mum Briana Jungwirth, "This is my first time away from Freddie so it's tough."
It's no surprise that Louis is missing his little man. He's made it clear over the past few weeks that he dotes on his son, calling himself 'Daddy Cool' during a backstage interview at the Brits which descended into chaos when bandmate Liam Payne got the giggles!
Aside from chatting about his baby boy, who was born in January, Louis has been sharing adorable photos of himself and Freddie - and if his facial expressions are anything to go by, Louis spends a lot of time gazing down at his newborn!
The latest heart-melting snap showed Freddie cradled by daddy's tattooed torso, Louis wrote: "Lad and Dad."
Proving Freddie is one seriously loved boy, Briana also told fans she's besotted with her new arrival calling Freddie "Love of my life."
Briana's pregnancy news surfaced in July and was confirmed by Louis in August, when he told a US TV show that he was "buzzing" to become a father.
The couple were never in a relationship but are believed to have shared a few dates earlier this year. Since then, Briana has stayed away from the limelight. She lives in California with her parents, and there have been reports that Louis was house hunting in a nearby area so he could be close to his son.
Louis, who is now dating actress Danielle Campbell, is rumoured to be replacing Nick Grimshaw on The X Factor panel this year, which could see him spending a lot more time back in the UK.
