DNA Tests Clear Keanu Reeves

Keanu Reeves can breathe a little easier ... turns out he's not the father of a Canadian woman's children.

DNA tests conclusively disprove claims by Karen Sala that Keanu fathered at least one of her four adult children, the actor's attorney tells TMZ.

Sala, 46, was seeking $150,000 per month in child support, retroactive from 1988 -- and $3 million a month in spousal support retroactive from 2006.

Reeves maintains he doesn't even know Sala.

She cites "irreconcilable differences."

According to the docs, Avril says they separated on Sept. 4th and were married 3 years and 1 month.

I invite anyone else who wants to recycle their old phone to join me.

That's my version of swift action with a higher purpose."
