Former Van Halen front man David Lee Roth has angered broadcast bosses with his diva antics on his new radio talk show.

The rock star, who replaced controversial shock jock Howard Stern when he moved to satellite radio company SIRIUS at the beginning of the year (06), is reportedly driving executives crazy with his demands.

One tells the New York Daily News, "This guy (Roth) is impossible to work with. A real arrogant, self-righteous a**."

Roth is less than enthusiastic about his new gig and never bothers to prepare for a show and leaves five minutes after he is finished.

The exec adds, "It's almost like he wants to get fired and take the money and run."

Roth also demanded expensive renovations to Stern's former radio studio and then refused to use it citing "asbestos contamination".

He also ripped down the walls of a temporary studio because he feared there was dust behind the walls.

The exec comments, "He swears he is allergic to dust and smoke, but (he) smells like an ashtray."

Before scoring his latest radio job, Roth was working as an emergency medical technician in New York City.
