As far as rolling out clothing lines go, Beyonce Knowles may not be your role model.

First, PETA sabotaged a dinner and laid into the bootylicious babe about her treatment of fur.

Now, Jay-Z's girlfriend has been slapped with a $1.5 million lawsuit by Manhattan businessman Greg Walker. He accuses Beyonce of breaching a contract and not paying him enough for brokering the launch of her clothing line, the House of Dereon.

Walker claims he introduced the former Child of Destiny - and her mother Tina - to Wear Me Apparel, Inc. (which is also named as a defendant) to help her get her fashion enterprise off the ground, but received "only" $25,000 from the family for the introductions.

Now, he wants a piece of the $15 million Knowles received from the licensing deal. While reps for Beyonce didn't comment on the issue, we have this to say:

Her new song, "Deja Vu," is really catchy.
