"Tracy Wyle and Noah Wyle, who separated in late October 2009, have confirmed they have entered into a mediation process," rep Eddie Michaels announced in a statement on the couple's behalf. "Neither has legally filed for divorce. Tracy and Noah live in separate residences; however their two children (Owen, 7, and Auden, 4) see both parents daily."
Wyle, best known as John Carter from NBC's hit ER, married makeup artist Tracy Warbin in 1998 after the couple met on the set of Myth of Fingerprints.
Says a friend of the couple: "They're cooperative with each other and have put the interests of their children ahead of anything else."
Wyle recently wrapped a TNT pilot for a sci-fi show, co-produced by Steven Spielberg and DreamWorks Television.
