Bar Rafaeli really seems to know how to make her ex jealous – by posting a photograph of herself in a tiny string bikini on Twitter.

If her former boyfriend Leonardo DiCaprio stumbles upon this picture, he’s sure to be regretting his decision.

The Israeli beauty then posted the photograph of herself on Twitter and wrote: ‘Yup! Can’t complain.’

She has been spending the past week in Cannes during the film festival and last night partied at the AMFAR Gala after Roberto Cavalli’s boutique opening the previous night.

But she faced embarrassment when she arrived in the same dress as fellow model Victoria Silvstedt, 36 at Cavalli’s bash.

The women managed to laugh about the fashion faux pas though and both looked stunning in the nude frock with sparkling bead detailing.

Bar accessorised her ensemble with a satin box clutch and nude patent heels alongside loose beachy blonde hair.

And seeing as she didn’t have a boyfriend to accompany her, Bar had a girls’ night out with her gorgeous friends.

After weeks of speculation, it was reported last week that DiCaprio and Miss Rafaeli had ended their on-off six year relationship amicably.

Apparently, after six years together, the pair are said to have decided they didn’t want to settle down.
