Rihanna apparently thinks Michelle Rodriguez's reported jealousy is "funny".

The Bajan singer is close friends with model Cara Delevingne, who has been dating actress Michelle since the beginning of the year.

Cara and Rihanna have been spending time together during this season's Fashion Weeks and it was claimed the model's girlfriend is less than happy about their cosiness.

"Rihanna told pals she thinks the whole thing is funny and pretty ridiculous," a source explained to British magazine Star.

"She's just friends with Cara, nothing more."

Cara, 21, has been making plenty of time for Michelle too and the pair recently jetted off to Thailand together.

But the Fast & Furious star, 35, is still thought to be unsure about her girlfriend's commitment.

"Michelle knows Cara is close to Rihanna but she thinks it's disrespectful for the two of them to be hanging out so much, especially as they've only just gone public with their relationship," the insider continued.

Rihanna is currently being linked to rapper Drake, who she enjoyed a fling with after splitting with ex-boyfriend Chris Brown in 2009.

It was recently reported that Michelle is very serious about her relationship with Cara.

“Cara might be younger than her, but she honestly thinks this is 'The One'. Just before she met Cara she was talking about wanting a family within the next couple of years,” a source previously told Mail Online.

“She really wants a baby and wants one soon and now she has found Cara she thinks this could finally be the time to chase that dream.”
