Chris Brown and Karrueche Tran have split up.

The controversial 25-year-old singer confirmed the news of their break-up during his Cali Christmas performance for radio station Power 106 on Friday (06.12.14).

While preparing to perform his hit single 'Loyal', Chris said: ''How many single ladies we got in here tonight? ''Well, I'm single, too. F*** that b***h.''

Karrueche also later confirmed the news via her Twitter account.

The on/off couple started living together in September this year after reuniting in August, with Karrueche splitting her time between her own property and Chris's.

A source said: ''When she's not travelling and working overseas, she's with Chris at his house most of the time.

''She's between her apartment in the valley and his house these days and for now, it's working out for them.''

At the time, however, it was said that the couple were keen to keep a low profile as they were uncertain about the future of their relationship.

The source added to HollywoodLife: ''They're still chilling and doing what they do but no, it's still not exactly clear on what the direction the relationship is going in.''
