Red Hot Chili Peppers bass player Flea says he ended up autographing some Metallica items following a mix-up at an airport in Belarus.

Flea has posted a picture on his Instagram account of him signing his name to a Metallica album, a DVD and pictures of the band.

He writes that the Chili Peppers tried to explain to the custom officials who asked for the autographs that they had the wrong band, "but they insisted that we sign anyway."

Flea says he did play a song with Metallica once, but adds that he's no Robert Trujillo, Metallica's bassist.
