The 'Hot Right Now' singer has formed a bond with the older model and is planning to jet off for a holiday in Ibiza with her, The Sun claims.
A source told the paper: “Rita sees Kate as an upgrade from Cara.
“She started to see Cara as a liability after she interrupted her set at a DKNY fashion show last month. Things have deteriorated since then.
“And she knows Kate can give her advice about making her career last decades.”
Cara and Rita are reportedly no longer on speaking terms following a cringeworthy performance at a DKNY party last month.
The Brit model stole the mic from the 'Shine Your Light' singer and gyrated with her on stage, which is reported to have angered Rita and the pair are said not to have spoken since.
An insider told The Mirror: "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."
The pair haven't been seen together since the party, and they have both been unusually quiet towards each other on Instagram and Twitter.
The Mirror also reported that the pair stayed just metres away from each other at Glastonbury last month but didn't party together.
Cara didn't seem too bothered though, as she was seen living it up with Rihanna on a private yacht in the south of France earlier this month.
According to the Daily Mail, the pair blew £300,000 on hiring the boat to sail them around the French Riviera with a further £200,000 for eating out and partying.
