Even eHarmony might have trouble with this one ... Edward Furlong -- who has a standing jail cell -- is now legally single and ready to mingle.
Furlong -- whose estranged wife, Rachael Kneeland, filed for divorce back in 2009 -- got the official court ruling this week that restores each of them to single status. They're still wrangling over money issues.
Furlong has a rich history of violating restraining orders and multiple arrests for domestic violence.
He also has an affinity for seafood ... he was arrested for throwing lobsters out of a grocery store tank because he wanted to liberate them.
Better hurry ... this one won't last.
