George Clinton's marriage has gone to the (atomic) dogs -- the funk legend has filed for divorce from his wife of 22 years, Stephanie Lynn Clinton, TMZ has learned.
According to docs filed in Florida court, the couple got hitched back in 1990 in Toledo, OH ... but have "experienced long term separation" throughout the marriage and say "the marriage is irretrievably broken."
According to docs, the couple has no children together, no shared property and no shared bank accounts. In fact, you'll hardly find any mention of Clinton even being married in the first place.
TMZ reached out to Clinton's rep for comment ... so far, no word back.
