The 24-year-old singer has already given Briana a three-bedroom home in Calabasas, California, and is renting his own lavish abode nearby in order to be close to his son.
He hasn't had a DNA test to prove paternity, but insists there is no doubt he is Freddie's father and he and Briana were dating exclusively when she got pregnant.
Louis flew back to the UK this week to attend the BRIT Awards in London and admitted it was hard being so far away from his little boy for the first time.
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."
