The superstar couple announced their separation on Mar 25 on Paltrow's lifestyle website 'Goop', reported Huffington Post.
"It is with hearts full of sadness that we have decided to separate. We have been working hard for well over a year, some of it together, some of it separated, to see what might have been possible between us, and we have come to the conclusion that while we love each other very much we will remain separate," read the statement on the website.
Martin, 37, Paltrow, 47, got married in 2003 and have two children together.
The couple asked for their privacy to be respected at this time.
"We have always conducted our relationship privately and we hope that as we consciously uncouple and coparent, we will be able to continue in the same manner," it said.
