Plumbers Crack Usher Over Shampoo Bowl

Usher's bathroom has ignited a war between the singer and the plumbers who worked on it -- and the next thing to be drained could be Usher's wallet.

Bobo Plumbing Company in Georgia claims they never got paid for the $2,335 worth of work they did on Usher's Georgia mansion back in 2007 -- work that included installing a shampoo bowl in the home's private salon and installing all the plumbing in one of his bathrooms.

But here's the catch -- Bobo's is now suing Usher, claiming if they don't get paid, they should have the right to sell the home and take their payment from the proceeds.
