Two rock worlds collided in a major way last night (Mar. 24), as Eddie Vedder was the special guest at Bruce Springsteen and the E Street Band's The River Tour stop in Seattle. The legendary rocker brought out the Pearl Jam frontman (who is the city's unofficial hero) to perform the Born in the USA classic "Bobby Jean."

It was fun to see Vedder bounce around the stage like a giddy teen as he sung the 1984 tune as he and Springsteen played off each other's warm-hearted vibes.

As Rolling Stone points out, this isn't the first time Vedder has rocked out with Springsteen. They have performed together at multiple concerts, including a cover of AC/DC's "Highway to Hell" in Australia back in 2014.

Springsteen will continue his tour on Mar. 28 at NYC's Madison Square Garden, while Pearl Jam plan to kick off their North American trek beginning April 8.
