Rapper and music mogul 50 Cent has dropped R+B singer Olivia from his G-Unit label. The hip-hop star confirmed her exit from his label on New York radio show MISS JONES IN THE MORNING last Wednesday (04APR07) - and has warned other acts on his roster that they all faced the axe if their albums flop. He says, "I made sacrifices constantly for the entire G-Unit (roster). At this point, they gotta do their thing now. It's their second album, everybody. If they don't deliver, then they don't actually work.
