Johnny Weir & Husband Do the Splits -- It's Over!!!

Johnny Weir has dropped the triple axel on his marriage -- splitting from his husband Victor Voronov after barely 2 years of marriage.

Johnny made the announcement today on Twitter, writing, "It is with great sadness that I announce that my husband and I are no longer together. My heart hurts, and I wish him well."

It's pretty sudden -- considering just last week, Victor was talking about getting down and dirty with Johnny ... in space.

But it's not exactly surprising -- the two have had their fair share of issues in the past, including an alleged domestic violence incident back in January ... during which Weir allegedly bit Voronov.
