Fourteen year old Miley Cyrus has already snagged a celebrity personal trainer. The wildly popular Hannah Montana star has hired fitness nut Harley Pasternak, who has trained celebs like Jessica Simpson. Miley is now on Harley’s famed 5-Factor Fitness and Diet Plan.

“She obviously doesn’t need to lose weight, she just wants to look great. She’s very motivated,” a supportive pal told In Touch.

Isn’t Miley a little young for a personal trainer, Harvey says no:

“We also work with Jane Fonda, so it’s a program that works for any age,” the fitness guru recently told In Touch Weekly.
