Country crooner Sara Evans announced on Thursday that she is quitting ABC's Dancing with the Stars, as she seeks a divorce from Craig Schelske, her husband of 13 years, with whom she has three children. "Recent events that shed light on the status of her marriage prompted Ms. Evans to make the filing," the singer's rep says in a statement to the AP. "[She is leaving DWTS] to give her family her full attention at this difficult time."
