Ivey and Luciaetta filed the joint petition in a Nevada court on December 22 ... three days before Christmas. The divorce was granted today -- both parties were present for the ruling.
Phil -- who's reportedly made more than $12 million playing poker -- married Luciaetta back in 2002. The couple has no children together.
Fun Fact: Ivey is known in the card community as the "Tiger Woods of Poker" -- [insert your own joke here].
