Karrueche Tran raised eyebrows after she posted a cryptic Twitter message stating that she is single.

The 26-year-old model who has an on/off relationship with boyfriend Chris Brown wrote on the microblogging website: "Looks like I'm a single lady again?"

However, Tran later clarified the tweet and revealed that she has joined American comedy-drama television series, Single Ladies on VH1.

The Say Goodbye singer reportedly started dating Tran amidst his romance with Rihanna. The two briefly split in October 2012 when Brown admitted he was "in love with two people."

Meanwhile, the couple had sparked rumours that Tran is pregnant with their first child, after their friend, Wackstar, posted a photo of the two on Instagram, and claimed they are expecting a baby.

The 25-year-old R&B star recently appeared on Hot 97's Ebro In The Morning radio show and expressed his love for Tran.

When asked how long they have been together, he replied: "Almost five years. Four and a half. She's straight I dig her, I dig her man, She's dope.

"I feel like especially being in this industry you need someone that understands you and understands who you are personally except for your name.

"You don't have to be buying them bags, let me stunt on you right quick. Although I do it because I love her, but that don't come with the territory, at the end of the day we have a real connection as best friends on top of our intimacy," Brown added.
