Louis Tomlinson 'preparing for custody battle' in major baby mama drama

LOUIS Tomlinson has been gushing about son Freddie Reign at every opportunity – but apparently, there's plenty of baby mama drama going on behind the scenes.

    PROUD DAD: Louis is allegedly gearing up for a battle to see his son

The One Direction star is reportedly readying himself for a custody battle amid claims that Briana Jungwirth is not letting him see their son.

LA-based stylist Briana gave birth to little Freddie last month, with Louis confirming the news on Twitter, calling the tot "healthy and pretty amazing".

But despite the boybander sharing pics with his baby boy, TMZ has alleged that Briana is using the one-month-old baby as leverage to get more child support from her ex.

   DRAMA: Sources have claimed Briana is not allowing Louis regular access to Freddie

The website alleges that sources told them that Louis is trying to get an order forcing Briana for custodial rights, including regular access to Freddie.

Tomlinson recently bought Briana a home in Calabasas to raise their son, and is renting a home in LA to be close to Freddie.

Louis, who is rumoured to be joining The X Factor as a judge this year, briefly dated Briana last year, but they are no longer together.
