Tomlinson's ex and the baby's mother Briana Jungwirth has told him not to pick their son Freddie up from her house after the 24-year-old singer turned up with current girlfriend Danielle Armstrong, reported Female First.
The singer's relationship with Jungwirth is said to have reached "rock bottom", with the final straw for the 23-year-old stylist being when the "Steal My Girl" hitmaker arrived at her house with Campbell in tow.
"Their relationship has hit rock bottom. He is not welcome at Briana or her family's homes anymore. Things are strained. Now he's picking up his son in a car park," said a source.
