The on-off couple were rumoured to have broken up earlier this month after Karrueche didn't accompany Chris to his court hearing in Los Angeles last week.
Usually, the petite model and stylist is pictured firmly by Chris' side as he heads to court, but when she wasn't seen with the R&B singer recently, speculation began swirling.
To add fuel to the fire, Karrueche was also thought to have started dating NBA player Brandon Jennings immediately following her supposed break-up with Chris, but she has now dismissed these reports.
Yesterday (5 March), the Vietnamese star tweeted: "Not dating anyone stop w the bs."
To make sure all of her fans and followers saw the announcement, Karrueche then posted a photo of her tweet on Instagram and added the caption: "Please and thank you."
Although she didn't directly comment on her relationship status with Chris, it seems safe to say that Karrueche is currently single.
This news comes after it was revealed last week that Chris has been diagnosed with bipolar disorder and will be continuing his treatment in rehab for another two months.
It is believed by a clinical team at the LA-based rehabilitation facility that the 24-year-old's previous violent behaviour was due to his bipolar and post traumatic stress disorder.
Karrueche had been supporting Chris throughout his treatment over the last few months and visited him frequently, even sharing a couple of rare photos of the two together over Christmas and New Year.
And the pair still appeared to be going strong earlier this year, as Karrueche opened up about her romance with Chris back in January.
She said: "It's different and it's something that a lot of people won't and will never understand, which is why I get so much flack and so much hate because looking from the outside in it looks messy."
Although the pair have broken-up and got back together a number of times (and survived a love triangle with Rihanna!), we wonder whether this split is for good.
