CNN anchor John King and correspondent Dana Bash have split after four years of marriage, the Washington Post’s Reliable Source reports.

Though still seen together in CNN reports, we’re told they’ve been living apart for the last several months. “They continue to co-parent their young son and to work together with the utmost professionalism,” their friend told us. “They ask that their privacy be respected during this difficult time.” Said another friend: “It’s been a very difficult process getting to this point, one that neither party wanted.”

King and Bash were married in May 2008. They have a 9-month-old baby boy, Jonah, born last June.
