Los Angeles: Chris Brown's on-off girlfriend Karrueche Tran has wished the R&B star the "best of luck" after ending the couple's romance following reports suggesting he secretly fathered a baby girl last year.

The 25-year-old 'Kiss Kiss' hitmaker has yet to address rumours he is the father of a nine-month-old daughter, who was born to a 31-year-old model friend named Nia, but Tran appears to have confirmed the news by tweeting goodbye to the singer.

In her Twitter post, she wrote, "Listen. One can only take so much. The best of luck to Chris and his family. No baby drama for me."

Nia and Brown have reportedly been friends for years and sources insist the pair is on good terms following the child's birth.

The baby's mother is also no stranger to Tran. A photo obtained by TMZ shows Tran posing with her arm around Nia at a party in Las Vegas in May, 2013, months before the model fell pregnant.

Brown and Tran have been romantically involved since 2011 and have previously overcome a brief love triangle with the singer's ex Rihanna.

They have also had to contend with his multiple legal woes, including probation violations which temporarily landed him behind bars last year.
