It's been a tough couple of months for Trace Adkins, and it looks like it's not getting better just yet. 

According to WSMV, Adkins' wife of 16 years, Rhonda, filed divorce papers citing "irreconcilable differences."

In the paperwork, she asks for custody of their three daughters. She also requested that Trace pay child support, alimony and all her legal fees.

Trace Adkins, who has battled alcohol abuse in the past, started off the year by entering rehab after an incident with an impersonator on a cruise.

In February, he left rehab to be with his ailing father who passed away at the beginning of the month. 

Trace made a surprise appearance at the Grand Ole Opry in March.
