Trace and Rhonda Adkins are getting a divorce after 16 years of marriage. According to TMZ, Rhonda Adkins filed the documents in Tennessee citing "irreconcilable differences" for the split. The documents state that she wants full custody of the pair's three daughters (aged 16, 12 and 9) as well as child support and alimony.
