Kim and Kourtney Kardashian made sure to pull out all the stops as they honoured their late father at a glittering event.

Robert Kardashian, who died of cancer in 2003 aged 59, was given a posthumous award by The Armenian Bar Association at a bash held at the Montage Hotel in Beverly Hills last night.

Kim, who is pregnant with her second child, wowed in a slinky silk dress with a daring thigh-high split.

Her sexy outfit flashed a lot of leg and a hint of cleavage and she teamed it with a nude-coloured jacket.

Her sister Kourtney was also there, and she opted to cover up in a flowing black dress which she glammed up by sweeping her hair back into a sleek up ‘do.

Kim took to Twitter to post pictures from the event, writing: “Thank you to The Armenian Bar Association for honouring my father last night!”

She also posted a picture showing her posing with sister Kourtney, as well as cousins Kara and Kourtni.

She said: “Thank u 2all of my cousins, aunts & uncle who came out to the Armenian Bar Association event.”
