La La and Carmelo's Anthony's marriage has been through a separation, a reconciliation, and years of speculation -- but now they've amicably decided to officially call it quits.
La La filed divorce docs Thursday in New York, 11 years after tying the knot with the NBA star, and cited irreconcilable differences.
Sources close to the former couple tell TMZ ... they've been separated for awhile but remain friends, as always, after 16 years together, and everything about the divorce is amicable.
We're told they both wanted to take time to ensure a private and smooth transition in their relationship for their 14-year-old son, Kiyan -- who's always their top priority -- and they remain fully aligned as parenting partners.
