Reason No. 147 why Kristen Stewart is too cool for school.

The 26-year-old actress stars in the latest Rolling Stones music video, a rousing cover of Eddie Taylor's 1955 blues hit, "Ride 'Em On Down." The track is the third to come off the legendary rockers' new all-cover album, Blue & Lonesome, released Friday.

In the three-minute clip, Stewart rocks a ripped T-shirt and blue jeans as she joyrides in a sleek turquoise '65 Mustang. In between smokes and a pit stop to gyrate near an abandoned gas station -- giving us a glimpse at her taut midsection -- the former Twilight star jams to the Rolling Stones track, driving erratically through the streets of Los Angeles. When she gets pulled over by a "police officer" in plain clothes, she utters one of the few lines she speaks in the video: "You should probably get out of here."

“It didn't take much more than a few words to get me amped on the idea," Stewart said in a statement. "The Stones. A '65 Mustang. Alone in Los Angeles. And the shoot was just as dreamy as the idea. We tore LA apart in a day and we had one hell of a soundtrack."

The actress also dons her new 'do in the clip, a slicked-back brunette coif that she debuted in November after several months of varying shades of blonde.

Stewart, who is now clearly in her element, recently stopped by The Ellen DeGeneres Show and admitted the discomfort she felt during her time starring in The Twilight Saga. "I was 17, 18, when it all went down and that was the most uncomfortable, terrible, weird thing," she explained. "At the same time it's good. It kind of forced me to stand to attention in this way, which, I didn't have that."

The actress says she is feeling far more "uninhibited" these days. "I think it takes a minute to sort of acclimate to communicating with so many people at one time," Stewart recently told ET. "I know people love to say, 'Oh, she doesn't give a...' like, no, I totally do, man! So yeah, I think I just feel a little bit more uninhibited or something."
