Louis Tomlinson is battling over his baby boy!

The One Direction singer is asking the judge for joint custody over his five-month-old son Freddie, claiming baby mama, Briana Jungwirth, is not letting him see his son because she hates his girlfriend. However, Briana says that the girlfriend poses a security risk to their child, reports TMZ.

The singer is requesting joint custody and equal access to his son since his mother has been denying Louis access to him. The Brit believes that Briana, who was never his girlfriend, is just jealous of his relationship with Danielle Campbell, and he says she's gone into a rage after seeing photos of the happy couple posted online.

Louis claims that he and his baby mama have been getting along swimmingly and that he got to see his son often -- until recently, when things have changed.

TMZ is reporting that Briana gets upset when Louis has the baby because when he comes back home he smells perfume. Apparently Briana's real issue is that she believes Danielle is a crazed fan who now knows her home address and gate security code.

Hmm ... we wonder how she feels about a woman having a baby with a pop star, she's not actually dating, just so she can have a baby with a pop star?

The outlet also reports that the possessive mom will be objecting to joint custody if Louis has a nanny because she feels that isn't true parenting, and she also does not want the baby to leave the U.S.
