7 Rock Stars Who Are Major Headaches Liam, Noel Gallagher count as one...which they'd probably fight about By Kate Seamons, Newser Staff Posted Jun 5, 2010 5:09 AM CDT 10 comments Comments Noel Gallagher: Probably quite glad not to share the frame with Liam. (AP Photo/Chris Pizzello, File) (Newser) – We expect rock stars to lay in beds covered in money while drinking insanely pricey liquor and, umm, doing some other stuff.

DMX: The rapper collects criminal charges (assault, animal cruelty, hijacking a car) the way your grandpa collects stamps. His manager once mysteriously got shot in the foot... Keith Moon: Sure, The Who's drummer liked to chuck TVs out of hotel windows. But his one true love was blowing up toilets using everything from cherry bombs to M-80s. Eric Clapton, circa 1971: In those days, the singer was downing so much booze and doing so many drugs that he'd wander off the stage mid-set, and have to be coaxed back on.
