The former Wilson Phillips star, who is married to actor Billy Baldwin, checked into an unnamed facility on her 42nd birthday (12Feb10) to help deal with personal issues.

She was released on Friday (26Feb10) after two weeks of treatment so she could be home in time to celebrate her daughter Jamieson's 10th birthday.

Phillips' manager, Lizzie Grubman, tells People.com, "After successfully completing her in-patient treatment for anxiety, Chynna Phillips has happily returned home to celebrate her daughter's birthday with her family and close friends. She's happy to be home with her family. (Rehab) was a positive experience for her. She's doing really well. She is in great spirits.

"Jamieson is having a slumber party with her friends to celebrate her birthday. Chynna is excited to be back with her kids and to celebrate her oldest child's birthday."
