Shooter Jennings, Keith Urban Get Wet and Wild

Actress Drea de Matteo showed support for rocker and boyfriend Shooter Jennings both onstage and off, taking pictures of the musician during his Sunday performance at the first-ever Rock'N the Rally music festival in Sturgis, South Dakota, and posing for a few herself, here with a Gibson Les Paul guitar.

Jennings' performance was one of several at the five-day event which coincides with the legendary annual Sturgis Bike Week. Keith Urban also rocked the stage that day, busting out an impromptu version of Creedence Clearwater Revival's 'Have You Ever Seen the Rain,' after a storm hit.

Rock'N the Rally continues through Aug. 10, with performances by Wolfmother and Nickelback tonight, Tom Petty and the Heartbreakers on Wednesday, and Sammy Hagar on Thursday.
