Rita Ora and Cara Delevingne not best friends anymore

Los Angeles: Singer Rita Ora and model Cara Delevingne have reportedly fallen out after the latter behaved in a weird manner at the DKNY`s fashion party.

At the event Delevingne snatched the microphone from Ora`s hands and grinded her, and now both of them are not on talking terms.

"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," mirror.co.uk quoted a source as saying.

"Rita`s been advised to distance herself from the model," the source added.

Delevingne was recently seen partying with singer Rihanna on a luxury yacht.
