The former The Jam frontman offered Gallagher a lift to visit his ex-Oasis bandmate Gem Archer after the guitarist suffered a broken leg and a fractured skull this summer (13).
But neither rock icon knew how to get to their destination, so they surprised a pedestrian by asking for directions.
Gallagher tells British radio station Xfm, "Weller just threw the satnav (Gps system) at me and said, 'Do you know how to work it?' Obviously I said 'no' - I don't even drive. I'm a world famous rock star, I've got people and a beautiful wife to do that for me. So off we go, with no idea of the route. Driving around north London, with me trying to tell him the right direction. He was cutting people up and calling them all sorts. We stopped to ask this lad if he knew where to go. He nearly had a heart attack when he saw us in the car."
