Country singer Garth Brooks is being sued by his former business partner, Lisa Sanderson, for being a horrible person with an inflated sense of self-worth.

That's not legalese, but you get the idea.

Sanderson's lawsuit alleges that while Brooks tries to present himself as "a humble and highly principled 'everyman,'" in reality he's a "paranoid, angry, deceitful and vindictive man who will turn against those closest to him on a dime."

She continues that she was brought on to "jump start" Brooks' TV and movie career, but even as a successful television producer, Sanderson couldn't save Brooks from himself.

The country star allegedly killed deals with Disney and Fox with his "ridiculous demands." For example, he was offered a role as a sniper in 'Saving Private Ryan' but refused to participate because "he wanted to be the star and was unwilling to share the limelight with ... Tom Hanks, Matt Damon, and Edward Burns."

She also claims he (and possibly his questionable goth alter-ego) turned down a part as the villain in 'Twister' because the real baddie was the CGI tornado. Okay then.

Sanderson is suing for $425,000 in unpaid salary, bonuses and punitive damages. We don't really care about her lawsuit -- but could we talk her into writing a book?
