Chris Brown's girlfriend has ended their relationship following rumours he secretly fathered a child with another woman.

The 'Loyal' hitmaker's long-term love Karrueche Tran says she wants nothing to do with his ''baby drama'' and has wished him and his family ''the best of luck.''

The stylist shared the news on Twitter, writing: ''Listen. One can only take so much. The best of luck to Chris and his family. No baby drama for me.''

The 25-year-old singer is said to have hooked up with their mutual friend, Nia Amey, 31, while he and Karrueche were on a break and now has a nine-month-old daughter with the model.

A representative for the star has yet to comment on the claims, but a source insists he is ''happy'' about being a father.

Insiders previously revealed Karrueche was ready to marry Chris, even if he is sent back to jail later this month after his probation was revoked in January.

Another source recently said: ''Of course she would marry Chris. There's not one man she would rather spend the rest of her life with other than Chris.

''She loves him that much and will be there for him no matter what happens in March. Obviously, she doesn't want him going to jail.

''She wants him home and in the studio so he can continue to inspire people with his music and his dancing and share his talents with the world.''

The singer allegedly broke the terms of his probation - which was set when he was convicted of assaulting then-girlfriend Rihanna in 2009 - by not finishing his community service and leaving town without permission.
