The night started with the group of ten ladies having cocktails in two adjoining suites in the hotel while the film crew for 'Keeping up with the Kardashians' put the final touches to the outdoor candlelit patio, where the group was set to dine a la carte while being filmed for the series.

Despite being Khloe's big night it was still all about the filming, with big sis Kim arriving twice at the hotel so they could get the camera shot right!

At around 8.30 p.m.  the party moved downstairs and the champagne was popped!

Khloe, Kim and the others wore all black and a ring of white and cream flowers around their heads with a piece of white lace hanging down the back.

"They all looked absolutely gorgeous," an eyewitness tells RadarOnline.com. But not everyone was completely happy.   “Kim couldn't wait to take her headpiece off as soon as she sat down and was almost forced into putting it back on, against her will, when it came to filming her and Khloe toasting."

"The dinner was very relaxed with a lot of eating, drinking and sharing old embarrassing stories. Tthere was a lot of laughing and giggling and reminiscing about childhood times."

A champagne toast was raised as the cake was brought out to celebrate Khloe's upcoming wedding, and all the girls cheered, there were even a few tears.

At this point the filming stopped and the real party began!

The ladies headed upstairs to their suites again and the private party went on until  2am, with the girls drinking and laughing.

The girls opened X-rated party gifts from Agent Provocateur, where Kim and Kourtney had been spotted shopping earlier in the day.
