Perhaps Kim Kardashian isn't quite the material girl after all.

The socialite, who turned 30 Thursday, canceled what was to be a surprise $1 million birthday cake in her honor after RadarOnline.com broke the news of the decadent delight.

"Kim was adamantly against accepting the cake," an organizer of the reality star's birthday festivities, GLO Night Club's Danielle Orsino, told RadarOnline.com exclusively. "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."

Kim Kardashian is about to take a bite worth a whole lot of money.

A New York jeweler has teamed up with a restaurateur to bake a diamond encrusted birthday cake, to be presented to the Keeping Up With The Kardashians star at a 30th birthday party for her at Glo Nightclub in Westbury, New York, on Saturday, RadarOnline.com has learned.

"The jeweler is going to encrust the cake with loose diamonds worth over a million dollars," Danielle Orsino, a spokesperson for Glo Nightclub, told RadarOnline.com.
