Two days after filing for divorce from actor Billy Baldwin, Chynna Phillips has had a change of heart.

Flashback: Chynna Phillips Checks Into Rehab for Anxiety

The 42-year-old singer/songwriter filed a divorce petition on Friday, seeking to end her 15-year marriage with the “Gossip Girl” actor. The former Wilson Phillips star filed the papers on the day she checked out off rehab. But on Sunday, Phillips decided to withdraw the petition so that she might save her marriage, according to the New York Post. “Chynna has gone under a lot of personal and professional stress,” an unnamed source said. “The divorce petition came after a long and emotional build-up. But once it was filed, she realized she didn’t want to lose Billy and asked her lawyers to withdraw it.”

“Every married couple has its up and downs, but they are two people who have been together for 18 years and are deeply in love,” Phillips’ manager Lizzie Grubman said. “They will work through their personal issues and they are committed to staying together.”

The couple have three children – Jameson, 10, Vance, 8, and Brooke, 5. Phillips is the half-sister of actress Mackenzie Phillips, who revealed last year that she carried on an incestuous affair with their father, John Phillips. The family revelation has reportedly taken its toll on Phillips.
