Model Karrueche apparently posted a message on her Facebook page: “Let me clear the air, if you have fenty at the end of ya name or your default Is Rihanna you have a better chance of winning the lottery than ending up on my friends list.”

She added: “I’m Angeline (sic), you’re Jen. C’mon you see where Brad is at.”

It is thought the 23-year-old was hitting back at her boyfriend’s ex, after RiRi posted a photo on Twitter last week of a bag of rice cakes wearing sunnies and hoop earrings.

Some thought the picture, which had the caption: “Ima make u my b****” (lyrics in her latest song, ‘Birthday Cake’) was Rihanna hitting out at Karrueche, who is Vietnamese.

However, Radar Online now reports that Karrueche says she doesn’t even have a Facebook page and hasn’t posted anything like that.

Rihanna also quoted lyrics from Lil Kim/Mob Deep’s ‘Quiet Storm’ remix in a tweet on Tuesday: “I’m a leader, yall on some followin s*** … coming in dis game on some modeling s***!”

Karrueche is a model. Cue gossip the tweet was another reference to Chris’ girlfriend.

There have been rumours that Rihanna and Chris were secretly seeing each other again, and speculation increased after the former couple released remixes of each other’s songs last month.

However, Chris’ rep insists he is just friends with RiRi and is still with Karrueche.
