Maybe Trace Adkins' drunken cruise ship bar brawl with a Trade Adkins impersonator was just too much for his wife. Less than three months after that insane incident, Rhonda Adkins has filed for divorce from her husband of almost 17 years, TMZ reports. She cited "irreconcilable differences," and it's not clear if Trace's alcohol problem (he just got out of rehab, according to the Los Angeles Times) has anything to do with it. She wants primary custody of their three daughters, child support, alimony, and—in what TMZ calls an "interesting" move—to be named sole beneficiary of Trace's life insurance policy. (In other celebrity marriage news, Robin Thicke recently told both E! and People he and estranged wife Paula Patton are "both very happy," though it's not clear whether a reconciliation is in the works.)
