Justin Bieber’s father has reportedly split from his partner of seven years.

The pop star’s dad Jeremy Bieber shares two children with Erin Wagner.

But according to MailOnline, the couple have called it quits due to Jeremy’s hard-partying ways.

The report claims the pair are living separately and sharing custody of Justin’s half-siblings, four-year-old Jaxon and five-year-old Jazmyn.

Sources told the outlet Erin, 27, was tired of Jeremy, 39, spending time partying with his son rather than being at home with his family.

“Justin hitting the big time in the way he has is an absolute dream come true for Jeremy and the temptation of being able to travel the globe, living like a superstar was too much to turn down,” a source told the outlet.

“Erin was always going to take second place to that. They are still on good terms for the sake of the children and she still has a great friendship with Justin, but their relationship has broken down. Jeremy has the opportunity to party with beautiful girls in every city in the world. He was never going to let anything get in the way of that.”

Jeremy has been the subject of scrutiny amid allegations he’s providing a poor example for his son, who has three court cases pending.

Rolling Stone, in its latest issue dissecting the “lightning-quick fall” of the pop star, reports Jeremy was present when Justin was arrested for DUI in Miami last month, and had accompanied him to a strip club two days prior.

According to MailOnline, Erin appeared to suggest things were rocky in a series of tweets weeks back in January.

“Hard to believe sometimes that things can get better! Trying to keep going!” she wrote in one message.

“Ready for the next chapter…..wonder what it’s about….#unknown,” she added in another.

Jeremy and Erin have yet to comment publicly about the claims.

Justin’s mother, Pattie Mallette, split from Jeremy when the future superstar was just 10 months old.

She later detailed their volatile relationship in her memoir, The Only Way Is Up.

Justin meanwhile faces charges of driving with an invalid licence and resisting arrest in Miami in addition to the DUI.

According to CNN, the Federal Aviation Administration is also investigating allegations the singer and his father interfered with crew on a charter flight from Canada to New Jersey for last month’s Super Bowl. A report from US Customs and Border Protection told the outlet the men ignored warnings to stop smoking marijuana onboard, while a law enforcement source told the outlet the pair were “extremely abusive verbally”.

The singer is also facing an assault charge in Toronto, where he recently handed himself in following claims he struck a limousine driver on the back of the head multiple times en route to a nightclub.

The outlet also reports Justin still faces a possible vandalism charge amid accusations he threw eggs at his neighbour’s home in Calabasas, California last month, causing an estimated $20,000 in damage.
