The bassist has been filling in for Tommy Stinson, who is currently on the road with his reunited group The Replacements, on five recent dates on the band's South American tour, and he will join the Sweet Child o' Mine hitmakers once more as they perform at the Club Nokia prizegiving in Los Angeles this week.
MCKagan originally quit Guns N' Roses in 1997, but he will be on hand to help Rose celebrate as the recipient of the 2014 Ronnie James Dio Lifetime Achievement Award.
Meanwhile, heavy rockers Suicide Silence will also debut a new member at the Golden Gods Awards after hiring Hernan 'Eddie' Hermida to replace late frontman Mitch Lucker following his death in a motorcycle accident in 2012. The gig will mark Hermida's first U.S. show with the group, which will also welcome former Sepultura co-founder Max Cavalera to the line up for a special performance.
Other artists due to take the stage at the Golden Gods Awards include Joan Jett and the Blackhearts, Zakk Wylde and The Pretty Reckless.
