Kim Kardashian blames sisters for her drunkedness!

Kim Kardashian only agreed to a boozy night out for her sister Khloe's birthday last year because she was tired of her sisters calling her boring.

Khloe treated her friends and family to a lavish booze-fuelled bash in Las Vegas when she turned 25 in June, and teamed up with her other sister Kourtney to convince Kim to join in the drinking.

However, Kim has vowed never to touch alcohol again - because she ended up with a massive hangover after the party.

She says, "The reason I got drunk then was thanks to my sisters pressuring me. Every night I'd be so tired of hearing them calling me boring for not drinking, I just wanted them to shut up. I certainly won't be repeating an evening like that. I mixed way too many drinks. I couldn't even get up the next day and I was so nauseous. I can't actually remember much from that night, so I have no idea if I did anything silly."

Wow, she really is spineless!!!
