Hip Hop Celebrity Impersonators

I`m planning a SURPRISE Sassy 16 Hip Hop Extravaganza for my daughter. I`ve been looking for celebrity impersonators since January and all I`ve found are Marilyn Monroe, Elvis Pressley and such... They don`t fit the profile for the HIP HOP EXTRAVAGANZA if you get my drift. My kid and her friends wouldn`t even know who those people are. I`d like Chris Brown, T.I, Omarion, Beyonce, etc. Can anyone put me in the right direction in So Jersey?
