The reality TV star whipped off her bikini top as she soaked up the sun on a Greek beach, having jetted off on holiday in the wake of her split from the lothario.

She has also been enjoying the sites of Crete in a jeep with pal and make-up artist Julia Whiteway, posting other snaps of their jaunt.
Lucy split with Spencer last month after the series finale of 'Made In Chelsea', when it it emerged he had cheated on her.
