The Iron Man star broke the news of the pair's "conscious uncoupling" to fans in March, 2014, and on Monday (20Apr15), she lodged papers in a U.S. court to make the split official.

The documents, which cite "irreconcilable differences" for the break-up, reveal the couple actually parted ways long before its 10th wedding anniversary in December, 2013.

Reports suggest the stars managed to work out a property and custody settlement before moving forward with the court proceedings to ensure a smooth divorce process.

Paltrow is seeking joint custody of their two children, daughter Apple and son Moses.
