Garth Brooks has filed a breach-of-contract lawsuit against an Oklahoma hospital in hopes that the country star will recover a $500,000 donation he made in 2005, reports TMZ. In the lawsuit, filed in Oklahoma, Brooks states that he gave $500,000 to Integris Canadian Valley Regional hospital in Yukon, Okla., with the agreement that it would be used for the construction of a new building to be named after his mother, Colleen, who died of cancer in 1999. He claims that hospital officials told him last year that the building would not be part of the hospital’s $27 million renovation project. A hospital rep told TMZ that it hopes the matter will come to a “swift and amicable end.” When contacted by, Brooks’ publicist confirmed her previous statement: “This deals with his mother, the home town and the people he grew up with and is deeply personal.”
