Kevin Federline’s dreams of Broadway stardom have crashed and burned with a resounding thud. The failed rapper now has the title of Broadway flop to add to his illustrious resume-which already includes golddigging and an unsuccessful turn as a backup dancer.

Producers of Broadway’s Legally Blonde: The Musical kicked K-Fed to the curb after the serial daddy made a number of outrageous demands and became an all-around displeasure to work with.

“The producers gave Kevin his walking papers,” an insider tells Star. “Kevin was acting like a Broadway diva, and he hasn’t even stepped onto the stage yet!”

“The producers got fed up with him.”

Kevin was scheduled to debut in the Tony-nominated producted in September, instead an emergency casting call has been sent out to fill Kevin’s trio of roles, including a dim-witted UPS man, the Star snitch adds.

Producers are desperately looking for someone to take Kevin’s place.
