GNR and Foo Fighters have been connected for a few years. Dave Grohl sat in with GNR last November on "Paradise City" during a show in Tulsa, Oklahoma.
Grohl also lent his famous "Rock Throne" to Rose when Rose broke his foot just a few shows into GNR's Not in This Lifetime Tour in 2016.
Foo Fighters will wrap up their European tour in a couple weeks. Get the remaining dates here.
Guns N' Roses' European tour continues through July. The band will have September and October off and then return to the road in Asia in November. Get the tour dates here.
