Kim Kardashian birthdayKim Kardashian knows how to party (and make some extra appearance fee cash along the way). The reality TV star celebrated her 30th birthday all over the continent with exclusive shindigs in Las Vegas, New York and Toronto.

The birthday girl, whose actual birthday is Oct. 21, didn't let all the partying go to her head though. She actually turned down an offer of a $1 million diamond-encrusted birthday cake. "I would never allow anyone to spend that much money on cake," Kardashian wrote on her blog. "Making a million dollar birthday cake is just ridiculous! I'd rather they gave me a cupcake and donate the rest of the money to the homeless."

Danielle Orsino of GLO Night Club in New York told Radar Online that Kardashian wasn't keen on the expensive cake. "Kim was adamantly against accepting the cake," Orsino said. "It's a shame that she couldn't just enjoy it for what it is, a record-breaking diamond-encrusted cake gifted her, a lover of diamonds."
