R+B star Beyonce Knowles has been slapped with a $1.5 million (GBP833,300) lawsuit over the launch of her House of Dereon clothing line. The singer is accused of breach of contract after failing to financially compensate businessman GREG WALKER enough after he introduced her to bosses at Wear Me Apparel Inc. Walker alleges the clothing firm paid Knowles "approximately $15 million" (GBP8.3 million) in a licensing deal, while his salary fell far shorter. The New York Daily News reports Walker received just $25,000 (GBP13,888) while Wear Me paid him only $85,000 (GBP47,222).
