MC Lyte’s marriage has hit the ultimate ruff patch … because the old school hip-hop icon is calling it quits.

Lyte, one of rap’s female pioneers, filed divorce docs in L.A. Monday, just 3 years after her marriage to Marine Corp veteran and entrepreneur, John Wyche.

As for the reason for the split … officially, according to docs, it’s the classic irreconcilable differences.

The couple wed at a beach resort in Montego Bay, Jamaica back in August 2017. The “Ruffneck” rapper said they met on Match.com and the relationship took off from there … but it probably didn’t last long enough for the dating site to brag about it.

The exes do not have any kids together.
