Brad Paisley is slated to join the many guest stars who have played with the Rolling Stones onstage during their 50 & Counting tour. The country star will jam with the legendary British rockers at their upcoming concert in Philadelphia on June 18.

The Stones made the announcement via Twitter on Thursday (June 13), asking, "What song do you think he'll play on?"

So far the tour to mark their 50th anniversary has featured appearances by musical luminaries as diverse as John Fogerty, Katy Perry and Dave Grohl. Keith Urban joined the group in Los Angeles on May 3 to perform 'Respectable,' and Carrie Underwood appeared with them on May 25 in Toronto for 'It's Only Rock 'n' Roll (But I Like It).' Taylor Swift joined them in Chicago on June 3 to sing 'As Tears Go By.'

Sheryl Crow also jammed with the band on 'All Down the Line' on May 31 in Chicago.

The 50 & Counting Tour will wrap its North American leg in Washington, D.C. on June 24.
