Keith Urban had a real rock star moment at the Rolling Stones concert at the Staples Center in Los Angeles last night (May 3).

Urban joined the legendary rock band onstage to perform 'Respectable' from their 1978 album 'Some Girls.' So it was a tale of two Keiths - Urban and Richards, knuckling down on their respective guitars. They rocked out, as you can see and hear in this fan-filmed footage from the gig.

Urban had tweeted about grabbing a bite to eat before the performance, and posted the photo below, featuring his beautiful wife Nicole Kidman.

He tweeted: "Just ate at ‪@EatChego‬ before the stones gig - THE best food!!!!!!!! -KU."

How he could eat before taking the stage with the greatest living rock band on the planet is beyond us! We guess he wasn't dealing with any nerves or butterflies in his stomach.

While Urban is a bonafide superstar in his own right, still! It's not every day you get to jam with the Stones on their 50 & Counting Tour, and that's just what he did. This is certainly a career-defining moment on the already impressive resume of the singer/guitarist/'American Idol' judge.

Here is the Stones' set list, if you are interested in seeing what else they played. They were also joined by singer and fashion plate Gwen Stefani for a track.
