It may be the most drawn out divorce in Hollywood history -- but after 10 1/2 years, Arnold Schwarzenegger and Maria Shriver are single again.
It went down Tuesday morning in L.A. Superior Court ... TMZ has learned. The divorce had been mediated by a private judge and that judge signed off on the divorce earlier this month, but it needed to be entered into the court system by a sitting judge, which happened this morning.
As for why this divorce took so long, it's a combination of lack of motivation and a very complicated property settlement agreement.
