Mick Jagger has been spotted with Jack White, sparking rumors that the two are collaborating on a new project.

Jagger and White were spotted this week at a concert by indie band Death From Above 1979 held at White's Third Man Records in Nashville.

Third Man includes a studio, record store, label offices and a novelties lounge.

The rumors stem from when, back in 2009, Rolling Stone followed up on the news that Keith Richards had laid down tracks with White.

Back then, Richards was somewhat evasive on whether White might produce the first Stones album since 2005's A Bigger Bang, though still very complimentary.

"I enjoy working with Jack," Richards said. "I know Jack pretty well. He's a lovely player."

Neither Jagger or White have spoken publically regarding any potential collaboration.
