EDDIE GRIFFIN FINALLY DIVORCED After 6 Months of Marriage

Eddie Griffin gave Kim Kardashian a run for her money ... for SHORTEST MARRIAGE EVER -- because after just six months of wedded bliss, the comedian is officially divorced.

TMZ broke the story ... Eddie tied the knot last September at a Vegas chapel -- with a woman named Nia Rivers -- and one month later, the couple filed a joint divorce petition, citing "irreconcilable differences."

A month after THAT, Griffin and Nia attempted a reconciliation -- but that was short-lived ... and last month, the divorce was finalized by a Nevada judge.

According to the docs, obtained by TMZ,  the couple is incompatible in marriage -- but the split was pretty amicable ... because both agreed to joint custody of their two-year-old child King Edward Griffin.

According to the docs, Nia will receive $2,500 in monthly child support.

One last thing -- the couple agreed that neither person would ever disclose details about the split ... whether in a book, a screenplay, or any media interviews. So much for that made-for-TV special.
