Garth Brooks is being sued by his former business partner of 20 years. Lisa Sanderson, a TV producer and CEO of his own Red Strokes Entertainment, claims Brooks owes her promised but unpaid salary and bonus money after she spent years trying to jump start his acting career.

In the suit, Sanderson says that Brooks claims to be "a humble and highly principled 'everyman'" when he's actually a "paranoid, angry, deceitful and vindictive man who will turn against those closest to him on a dime."

Sanderson says the superstar ruined deals she worked to put together with Disney, Fox and others by letting his ego get in the way and making outlandish demands. She claims Brooks was offered a part as a sniper in Saving Private Ryan, but turned it down because "he wanted to be the star and was unwilling to share the limelight with . . . Tom Hanks, Matt Damon, and Edward Burns."

Sanderson also lined up a part in the movie Twister for Brooks, but alleges he, again, wanted to be the star.

Sanderson is seeking $425,000, in addition to punitive damages.

TMZ reports that Sanderson also says Garth is a tax fraud.

Yesterday afternoon (Monday, April 15th), a spokesperson for Red Strokes Entertainment Inc. issued a statement saying, "Mr. Brooks, of course, denies everything in the lawsuit filed today by Lisa Sanderson. Mr. Brooks and Red Stokes Entertainment Inc. will continue to take the necessary steps toward resolving this matter through the legal system."
