Are the Rolling Stones gearing up for another tour? Possibly.

Keith Richards says he's going to meet up with Ronnie Wood and Charlie Watts at a London studio sometime this month...and Mick Jagger might show up, too.

Keith says, "We're just going to play a little together, because we haven't played for three or four years. You don't necessarily want to rehearse or write anything, you just want to touch bases. We just want to get our chops down."

So it sounds like the Stones may very well be planning a 50th anniversary tour for next year. If it happens, it'd be their first shows in five years, since their Bigger Bang tour ended in 2007. Nothing is official yet, though.

Ronnie says, "I just hope we can perform live. It'd be great to see if that old spark is there."
