Filming began last week for the 5th season of "Basketball Wives," but Shaunie O'Neal, Evelyn Lozada, Tami Roman. and Suzie Ketcham do not have locked contracts.

According to sources, the "Wives" are in the process of renegotiating their contracts and they all want major pay raises, claiming the show does quite well for the network.

VH1 is reportedly refusing to pony up more cash. Before filming started, execs made it clear that salary increases would not happen and if any cast member had a problem with that they could be replaced. 

So far, a deal has not been reached and neither side is budging, and the "Wives" are reportedly planning to walk out next week if VH1 can't agree to the terms.
