Taylor Swift is featured in the new issue of PEOPLE magazine as one of 'Hollywood's Richest Kids.' The teen sensation has sold more than 3 million copies of her self-titled debut album. But don't expect her to drop her cash on frivolous purchases.

"I'd rather put money back into my career than buy a Lamborghini," Swift tells PEOPLE.

Swift says that her biggest splurge has been a million-dollar tour bus, complete with a fake fireplace. She's joined on the 'Richest Kids' list by the Jonas Brothers, Zac Efron,'Harry Potter' actor Daniel Radcliffe and Miley Cyrus, who tops the list with an expected billion-dollar worth by the end of this year.

Swift will be in Los Angeles this weekend to receive the 'Superstar of Tomorrow' award at the 10th Annual Young Hollywood Awards. She is the first musician to ever receive the honor, as it has always gone to an actor or actress in past ceremonies.
