Carmelo and La La Anthony are separated ... TMZ has learned.
Sources close to the couple tell us the actress and NBA superstar are now living separately. La La moved out of the family home last week and has her own place in NYC now.
We're told the couple's had ups and downs in the past, but the current NBA season has been extremely stressful on the marriage for several months. Carmelo's been plagued by trade talks ... with the Knicks looking to move him to another team.
Our sources say the split is still amicable.
