The 'Keeping Up With the Kardashians' star went to bed a little intoxicated last night after the 32-year-old model and her husband John Legend arranged for the nifty gadget, which included an "unlimited supply of Moet", to be delivered to her house.

Taking to her Instagram account, the 62-year-old momager uploaded a photograph of the lavish vending machine propped outside her home with the champagne in boxes.

She accompanied the shot with the caption: "Umm thank you @chrissyteigen @johnlegend @jenatkinhair @mrmikerosenthal ...When a forklift shows up at my house on Monday morning with a Champagne Vending Machine and an unlimited supply of @moetusa @moetchandon Champagne i am jumping for joy!!! And I'm not gonna lie a little drunk. I LOVE you guys thank you my beautiful friends #ilovechampagne #ilovemyfriends #blessed #luckygirl (sic)."

And the matriarch no doubt needed a glass or two of champagne to relax after spending the weekend running around after her nine grandchildren and their friends at North and Penelope's joint unicorn birthday party.

Kris' daughters Kim Kardashian West and Kourtney Kardashian organised the lavish party for North - who will be five on June 15 - and Penelope, who turns six on July 9.

The children could ride on ponies dressed up as unicorns with coloured horns attached to their heads, which Kim joked were "real unicorns, guys".

The party food included a unicorn cake, unicorn-shaped ice-creams and cookies, a rainbow Maypole and elaborate table decorations.

The two birthday girls played in a pool filled with inflatable rainbows and the entertainment was provided by DJ Livia, a 10-year-old DJ.
