Louis Tomlinson's Son: Master of His Own Domain

Louis Tomlinson's 1-week-old son doesn't have to worry about his name being pimped out on the Internet, thanks to his mom's family.

Briana Jungwirth's family registered FreddieTomlinson.com on January 27th ... minutes after Louis and Briana first revealed baby Freddie to the world.

Sources close to the couple tell us once the baby's name was revealed, One Direction fans started creating bogus social media accounts with Freddie's name, and pretended to be associated with the family.

We're told Briana's family wanted to protect the kid's best interests and block any squatters -- after all, he is 1D royalty. Baby Freddie's now free to focus on important things like pooping and breastfeeding.

Not necessarily in that order.
