"Over the past few months we've come to the conclusion that the best way forward for us as a family is to separate as a couple. It is with great love, respect, and friendship in our hearts that we look forward to raising our children together and exploring this new phase of our relationship," Watts and Schreiber told ET in a joint statement last week. 

"While we appreciate your curiosity and support, we ask the press to be mindful of our children and respect their right to privacy,” the former couple added.
