(NEW YORK) -- Kim Kardashian is many things: beautiful and business-savvy, popular on both Twitter and TV.
But a role model for smart spending? Maybe not.
The Keeping Up With the Kardashians star celebrated the launch of the Kardashian Prepaid MasterCard at New York City's Pacha nightclub Tuesday. Clad in a skintight dress appropriately adorned with sequins the color of coins, Kardashian, 30, and her sisters, Khloe Kardashian, 26, and Kourtney Kardashian, 31, gushed to Entertainment Tonight about their love of spending money.
When asked which one of the trio spends the most, Kourtney said, "No question, it's Kim." Kim, who once admitted to spending $2,500 on a pair of lace-and-python Christian Louboutin booties, nodded her head in agreement.
Kim and her sisters teamed with MasterCard to create a prepaid credit card for teens as young as 13 years old. The card allows parents to put a predetermined amount of money on the card, then track their teens' spending habits via cell phone.
Despite the Kardashian clan's lavish lifestyle, Mobile Resource, the company releasing the card, believes the family can breed budget-friendly spending habits in their fans.
"It is clear that the Kardashians are very wealthy, Kim also just spent $30,000 on a purse," a representative for Mobile Resource said in a statement to ABCNews.com. "They can well afford their expenditures. They wanted to take state of the art technology to their fan base, providing them with a vehicle to protect their money and control and track their spending with all instant alerts to their cell phone."
Still, spending money was the message at Tuesday's party. Shortly after arriving at Pacha, Kim tweeted a message to her more than five million followers: "Thx 4 coming out 2 support our Kardashian MasterKard! Let's go shopping!"
