Curb Records has filed suit against Tim McGraw claiming breach-of-contract. From my friends on the inside this is the straw that broke the MGraw's back. Don't look for him to be back at the label where both parties made gold. Now expect Tim to kick himself to the proverbial (pardon the pun) curb! At least that's what I'm predicting, by what some close friends are saying "off the record" though.
