Richards, who is releasing a new solo album, Crosseyed Heart, on Friday, said in a live question-and-answer session that he was in London last week and got together with Mick Jagger, Charlie Watts and Ronnie Wood.
The band, which finished a North America tour this summer, will tour South America in early 2016.

Richards has made no secret of his ambition to get the band back to work on a new album. “I’m trying to get the Stones into the studio,” Richards recently told EW. “But I don’t quite honestly see it happen this year. After we do South America in February and March, I’d love to get in the studio in April. But I know what those guys are like. When they finish a tour, they don’t want to do nothing!”
Crosseyed Heart is Richards’ first solo album since 1992's Main Offender. Richards shared the album track "Trouble" back in mid-July.
