"We had just finished dinner and were at the hotel bar to watch the Lakers game when Scott Stapp walked in being very loud and obnoxious," Martinez tells Rolling Stone. "In fact, one of the first things he said was that he loved to fight. So he started doing shots and breaking the glass on the bar, almost hitting one of our crew guys. My wife and I moved to a table and eventually Scott made his way over and sat down. He was looking for attention. Even before that, he had wadded up a napkin that he lobbed in our direction. It was pathetic, and we tried to ignore him, but it was impossible. Then he made a pretty disrespectful comment to my wife, which I'd rather not repeat, but in no uncertain terms, the word 'fuck' was used. That's when [drummer] Chad [Sexton] walked over."

"From the moment he walked into the studio, he was rude, belligerent and drunk," reports a Lowdown spy. "With Beth, he was nothing but extremely mean, sexist and an all-around jerk."

Another source says that even with his publicist in tow, Stapp cursed "every other word," called a female executive producer a "b-," constantly flipped the bird, and referred to Ostrosky - better known as Howard Stern's longtime girlfriend - as a "bimbo."

Stapp also couldn't resist taking swipes at his more famous rock colleagues. "I met [U2's] Bono and The Edge, and Bono was an a- to me," he declared, before insulting Foo Fighters front man Dave Grohl's manhood as "freaking little."

When a crew member accidently bumped into him on the set and quickly said he was sorry, Stapp snapped, "Yeah, you better f-ing be."
