Rob Kardashian and ex-girlfriend Black Chyna have agreed on a custody arrangement for their daughter Dream.

It's emerged that they have an unwritten agreement where they each get 50 per cent physical custody and have no plan to get a formal arrangement from the courts.

A source told TMZ that the arrangement is "loose" and that Rob currently has the little girl four days a week.

Rob and Chyna are in agreement when it comes to child-rearing decisions, according to the source, putting Dream ahead of any animosity between them.

Happy Fathers Day @robKardashian ?

The pair, who were together for a little over a year, hit headlines last week when Rob lashed out at Chyna on social media. The reality star posted a slew of intimate photos of his ex on Instagram, as well as a torrent of abuse accusing her of cheating. Many commentators have criticised his actions, branding the leaks 'revenge porn'. In response, Chyna accused Rob of violence towards her and was successful in getting a restraining order against him. Chyna told Good Morning America, however, that she would not be looking for full custody of their daughter. “I would never try to take Dream from her dad,” she said. “Hopefully, me and Rob can learn to have common ground and be the best co-parents as we can be.”
