And insider allegedly told the tab, "There's a lot of hurt on both sides but Rita's been working towards her singing career and carefully crafting her image for four years and it was all in danger of being a joke after that shabby performance. Rita's been advised to distance herself from the model." Ouch!
The singer, who's currently loved up with DJ Calvin Harris, has admitted recently that her real mates are the ones she's known her whole life.
Reets told GQ, "To me, I have my friends who I've known my whole life, and I can count them on one hand.
"They're people I went to school with. Everyone else I meet from that point on, if they happen to become a friend, that's incredible - come and join the family - but if not..." Could this mean that Cara was a mere flash in the friendship pan?
Ah well, looks like the model of the moment has found a new pal in Rihanna anyway.
