Oh Leo... SURE you don't want to rethink your decision? Newly single Bar Refaeli unveils her top model bikini body

Bar Refaeli 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 25-year-old model lay back on a cream leather couch aboard a super yacht in a black triangle bikini top and string pink and black bikini bottom.

TOWIE's Lauren Goodger shows off her bikini body as she and fiancé Mark lark around in the Spanish sun

The reality show that made their names is currently off air - but The Only Way Is Essex sweethearts Lauren Goodger and Mark Wright won't be finding themselves out of the headlines any time soon. 

The pair were enjoying some time off in Alicante last week following the end of the second series a fortnight ago - but seemed to be behaving as if they were still being filmed for the show.

The engaged couple hired a luxury motor boat and then larked about in a series of poses that would have looked somewhat staged if they hadn't simply been taking a few days holiday.
