Randy Travis just can't seem to shake trouble!   His ex-wife and former manager, Elizabeth Travis, has filed a lawsuit alleging a breach of the couple's post-divorce management contract.  The Nashville Business Journal says the suit filed last week, claims Randy "intentionally interfered with" the ability of Elizabeth Travis to do her job and undermined the "effectiveness of [his] career in the entertainment industry."     Other documents filed last week also charge that Randy and his attorneys terminated the agreement without written notice.    The lawsuit alleges that the entertainer, who married Elizabeth "Lib" Hatcher in 1991, "had a large truck, an armed guard and several other men" appear at her Music Row office and that the men removed "practically all of the property and business records," from the office, including computers and framed record plaque.   In a statement issued by his publicist, reported by The Boot, Randy responds: "It is unfortunate that it's come to this. We believe the lawsuit lacks merit and that we have legal defenses to her claims."    No dollar amount is specified in the suit.  Read all about it here.   Randy was arrested in February after the Super Bowl for public intoxication.  He issued an apology afterward, saying he would take full responsibility for his actions.
