It's Sir Elton John vs. Madonna—round two.
Elton and Madonna will be going head-to-head at the Super Bowl. Madonna is singing at halftime. Elton sings in a commerical for Pepsi.
Still in costume from his commercial, Sir Elton told Good Morning America his advice for Madonna which was, "Make sure you lip sync good."
Ouch! Their feud boiled over at the Golden Globes when Madonna beat Elton for the best song and things got a little mean on the red carpet.
Sir Elton said, "Madonna hasn't got a (blanking) chance."
From the looks of this interview, there's still some bad blood.
