Kim took the snaps during her stay in Miami at the Versace mansion. David and Victoria were recently rumoured to be buying the glamorous home.

The mum-of-one took the snaps in the bathroom of the mansion.

Kim was trying on 16-year-old sister Kylie Jenner’s black bikini and she liked it so much she hinted that she as planning on keeping the two-piece.

She shared the pic with the caption: ‘Yep stole Kylie's bikini...she's not getting it back.’

Even though Kylie’s bikini could barely handle Kim’s impressive curves, she told fans in her next selfie that she was planning to attempt a swim in the bathing suit.

‘Quick swim before the Dash party!’ Kim wrote. Kim was in Miami to attend a party for the Kardashian’s boutique DASH.

She was sure to promote the fashion brand with selfie wearing a piece from her own collection.

‘Today's Look- #KardashianKollectionCroppedTurtleneck #VintageAlaiaDress #AlaiaHeels.’

Kim looked slimmer than ever in her party wear- it looks like her new gym obsession is clearly paying off!
