DANVILLE, Ky. (AP) — Country music star Eddie Montgomery's steak house may have once been something to be proud of, but now the closed establishment is something causing him legal problems.

Central Bank and Trust Co. of Lexington has sued Montgomery and his ex-wife, Tracy Nunan in Boyle Circuit Court, claiming the couple owes nearly $12.7 million to pay off loans related to the business.

The Advocate-Messenger reported (http://bit.ly/16YD0Cl) that Montgomery and Nunan personally guaranteed repayment of several loans. Eddie Montgomery's Steak House closed in May.

Montgomery was half of the duo Montgomery Gentry, which had a string of hits for Columbia Records' Nashville division between 1999 and 2008, including "Lucky Man" and "Something to Be Proud of."

Neither Montgomery nor Nunan could be reached for comment.

After initial attempts to locate the restaurant in Danville, Eddie Montgomery's Steak House opened with much fanfare in Harrodsburg in late 2009. After the couple divorced a year later, the restaurant went to Nunan as part of the settlement.

Central Bank asks the court to immediately turn over management of the restaurant and other properties to the bank so they may be sold at Master Commissioner sales in Boyle and Mercer counties.

The lawsuit states Montgomery now lives on Old Bridge Road in Boyle County and Nunan lives in Lexington with her husband, Nicholas Nunan, who is also named as a defendant in the complaint.

Montgomery Gentry released six studio albums and a greatest hits package for Columbia Records' Nashville division between 1999 and 2008, spawning more than 20 singles that charted on Billboard Hot Country Songs.

The duo left Columbia Records in 2010 after an album titled "Freedom" and another extended play disc were shelved. The band signed to Average Joes Entertainment. The duo's most recent full-length record, "Rebels on the Run," on that label in October 2011.
