Who needs a college degree when fame and fortune awaits?

Since their first appearance on "Keeping Up With the Kardashians" in 2007, Kendall and Kylie Jenner have become stars in their own right, thanks to lucrative modeling campaigns and a thriving teen fashion empire.

When Us Weekly spoke to their father Bruce Jenner at the Performance 3D demonstration in New York on Monday, the 62-year-old Olympian admitted his girls' careers are so busy they may not pursue higher education.

"If they want to go to college, certainly, I think it's a good idea. But I'm not the advocate of, 'You've got to go to college!'" Bruce said. "I think by the time they graduate from high school, they will probably be in a position to go right to working."

Like their older sisters Kourtney, 32, Kim, 31, and Khloe, 27, Kendall and Kylie are becoming branded businesswomen, Bruce explained. "They're just developing their clothing line for Sears -- it's a little more teen-oriented, the clothing line. And they're working all the time on the show."

With two magazine covers under her belt (American Cheerleader and Teen Prom), Kendall, 16, is poised to become the next big supermodel, Bruce added.

"She'll probably have a career by the time she's out of high school," Bruce told Us. "If that's what she wants to do, that's good. I don't know if college is going to be that important for her."
