Bass player Duff McKagan has hinted that Guns N' Roses may be reuniting for an upcoming tour.

The 50-year-old rocker posted a message to fans on Monday that read: "Argentina, Paraguay, Bolivia, Brazil! See y'all in the next few weeks, Si (yes)? GNR."

If the tweet is true, it means McKagan will join the tour in Buenos Aires on April 6 and would mark a return to a band he quit all of 14 years ago.

McKagan quit Guns N' Roses in 1997, but was inducted with the rest of the band’s original line-up into the Rock & Roll Hall of Fame in 2012.

But only Slash, McKagan, Steven Adler and his 1990 replacement Matt Sorum attended the event, with original lead singer Axl Rose a no-show.

In addition to his musical career, McKagan has established himself as a writer and also founded the wealth management firm Meridian Rock

It was reported in February that Rose had possible plans for a Guns N' Roses Las Vegas residency.
