Comedian John Mulaney officially filed for divorce Friday from artist Anna Marie Tendler in New York court. The couple has been on the rocks for months, with Mulaney struggling to remain sober during coronavirus lockdown, checking into rehab in December to deal with alcohol and cocaine addiction, and asking for a divorce in February. He has been linked to actress Olivia Munn after informally separating from Tendler, whom he married in July 2014.
