Singer Chynna Phillips, best known for her work with the trio Wilson Philips, has called off her divorce to husband Billy Baldwin.

Phillips, who had spent a month in a rehabilitation center to reportedly treat anxiety issues, had filed to end her 18-year divorce from Baldwin one week ago; a move that the in-production film "Gossip Girl" actor claimed was stunning and unexpected.

The precise grounds for Philip’s divorce filing are unclear, and may remain that way. According to a source published in the New York Post: “Chynna has gone under a lot of personal and professional stress. The divorce petition came after a long and emotional buildup. But once it was filed, she realized she didn’t want to lose Billy and asked her lawyers to withdraw it.”

Philip’s publicist has stated clearly that the divorce is now a non-issue. “She filed and withdrew,” her publicist said. “They are going to work out their issues.”
