Kim Kardashian shows off her curvy figure in tiny striped bikini as she spends time with sister Kourtney in Miami



Kim Kardashian has been spending a lot of time in Miami recently, but who can blame her when she has a bikini body like this?

The 29-year-old socialite wore a tiny purple and white striped triangle bikini as she strolled along with beach with her 31-year-old sister earlier this week.

Wearing dark sunglasses and carrying a sarong, Kim showed off her enviable figure in the two-piece, which drew particular attention to her most famous asset - her curvy bottom.

But, as she finished her fifth consecutive day of intense workouts, Kourtney passed out and had to be treated by paramedics in an ambulance.

Sister Khloe was then called to pick up her ill sibling, and didn't hold back in reprimanding her for her crazy obsession with her weight.

Afterwards, Kourtney said: 'I've been obsessing about this weight thing a little too much. I'm so embarrassed that I punished my body for a photo shoot.'

Kourtney and Khloe are currently in Miami filming their reality series - a followup to the original fly-on-the-wall series Keeping Up With The Kardashians.

However, all three sisters attended friends New Orleans Saint Bobby McCray and Khadijah Haqq's wedding this weekend.

But things were a bit awkward as Kim, who looked stunning in a tight pale pink dress, was forced to deal with ex-boyfriend Reggie Bush, who was acting as a groomsman for the ceremony.

Khloe is believed to be on the brink of getting her own reality show, following her life with husband Lamar Odom, although a representative for E! Entertainment Television has yet to confirm the reports.
