Kim Kardashian is belle of the Vienna Opera Ball

Kim Kardashian attended the Vienna Annual Opera Ball on Thursday evening, accompanying billionaire mogul Richard Lugner.

The reality TV star was breathtaking in a floor-length gown from Ralph Rucci's SS14 collection which she chose for the grand occasion.

The show-stopping dress, featuring a black top with sheer and opaque panels and a full satin, blush pink skirt, perfectly accentuated her voluptuous figure.

A pair of hot pink Christian Dior heels finished the sophisticated look, along with smokey eye make-up and poker straight hair.

Stylish Kim was reportedly paid $500,000 for being the guest of honour of 81-year-old businessman Richard.

But it seems the pair didn't hit it off. During the evening the mall developer told reporters that Kim was "annoying" him because she wasn't "sticking to the program" – leaving him while she filmed scenes for E! reality show Keeping Up with the Kardashians alongside her mum Kris Jenner instead.

Just hours after her arrival, the Austrian magnate told press that the reality star had stood him up to go to a Schnitzel restaurant with the Kardashian matriarch, reported Radar Online.

Meanwhile, Kim is understood not to have been enamoured with her date, either, as he was "aggressive" and didn't like the company of her security.

Richard, who has a long history of paying starlets to accompany him to Vienna's annual Opera Ball, was joined by Paris Hilton in 2007.

Carmen Electra, singer Geri Halliwell and Dita Von Teese have also flown to Vienna to be with the business owner for the glamorous event.
