American badass Kid Rock joined John Mellencamp for a duet on the heartland rocker's "Pink Houses" during Tiger Jam IV, a charity event hosted by Tiger Woods in Las Vegas on Saturday.

Mellencamp's set, which also featured "Small Town" and "Jack and Diane," topped off a day of fund-raising activities for the Tiger Woods Foundation, which uses golf clinics and workshops to help young people gain self-confidence and realize their potential, according to a statement from the organization. Third Eye Blind also played a 10-song set that included "Graduate" and "Semi-Charmed Life."

The event at the Mandalay Bay Resort & Casino raised more than $1 million for the foundation.
