After nearly 17 years of marriage, country music star Trace Adkins and his wife Rhonda Adkins are going their separate ways, ET has learned.
In court documents filed by Rhonda in Tennessee on Monday, irreconcilable differences are cited as the reason for the split.
The estranged couple has three daughters, whom Rhonda has asked to have primary residential custody over. The daughters' ages are 16, 12 and 9.
Trace, 52, checked into rehab in January following a "setback in his battle with alcoholism" while headlining a country cruise to Jamaica.
Trace reportedly got into an altercation with a Trace Adkins impersonator who was doing karaoke in a bar on the ship. Trace checked into a treatment facility after the cruise ship arrived in Jamaica.
It is unclear if Trace's struggles with alcohol have anything to do with the breakup.
