Louis Tomlinson is not happy with those invading his son's privacy.
In a letter from Tomlinson's reps on Friday, which ET has obtained, the One Direction singer scolds paparazzi and media outlets and pleads for increased privacy for his 6-month-old son, Freddie.

Sent days after Tomlinson filed for joint physical and legal custody of his son with Freddie's mother, Briana Jungwirth, the letter argues that the media attention has greatly inhibited Freddie's right to have "a normal, private and protected childhood."
"The persistent and increasing levels of paparazzi and media intrusions into Freddie's life of late are not only posing potential security issues but are also crucially invading the privacy to which Freddie is undoubtedly entitled as a child," the letter states. "The levels of paparazzi attention on Freddie are intolerable and completely unjustifiable."
According to the letter, photographers and paparazzi have been invading Freddie's privacy on a daily basis, taking photos of private moments during Tomlinson's visitation time with his son, as well as at doctor's appointments. The letter also states that photographers have followed Freddie even when he isn't with his famous father.
