CHRIS BROWN never married his ex but their split is still costing him some serious cash.

The singer has handed a lump sum to KARRUECHE TRAN so she can buy herself a house.

The couple broke up last week over his friendship with RIHANNA.

The Bajan has been on her best behaviour too since her ex-boyfriend’s break-up.

A source said: “Neither Rihanna nor Chris want to make things harder for her than they already are.

“Chris wants to set her up financially and do right by her – he wants her to stay in his life if possible.

“Rihanna called Karrueche for a proper heart-to-heart. They needed to air a few problems.

“The girls talked for close to two hours. Rih answered all of the questions and Karrueche had a few home truths to tell her.”

He’s a real charmer Chris Broon. Bin the missus for the ex who you beat up, then hand over a suitcase of wedge. Lovely.
