Russell Brand has filed for divorce from Katy Perry ... TMZ has learned.
In the docs, filed in L.A., Brand cites "irreconcilable differences." The two were married Oct. 23, 2010 in India. They have no kids.
Sources had told TMZ the couple was having problems, evidenced by the fact that they spent Christmas apart and neither was wearing a wedding ring.
Although it's not 100%, based on what we now know it appears Brand may have blindsided Perry by filing the divorce petition.
Russell appeared on "Ellen" just this month, slamming divorce rumors -- claiming, "I'm really happily married ... Iím married to Katy. Perpetually, until death do us part was the pledge. Iím still alive."
