MARK SHOULD MIND HIS MANNERS!

"Extra" host and "Sugar Ray" singer MARK MCGRATH held court with a bunch of buddies at Hollywood's Green Door on Jan. 31 – looking like he'd just returned from a visit with the Botox doctor! His face looked stiff. Even worse, the frozen-faced rocker rudely dissed a fan who tried to approach him – and he and his pals laughed mockingly as she skulked away. Learn some manners, Mark!
