Singer/songwriter Chynna Phillips has checked herself into rehab for anxiety treatment.
The former Wilson Phillips star, who is married to actor Billy Baldwin, was taken to an unknown facility over the weekend (13/14Feb10), according to her manager Lizzie Grubman.
She tells People.com, "After much thoughtful deliberation Chynna Phillips has checked herself into an undisclosed treatment facility for anxiety.
"With the full support of her family and friends, she is looking forward to her recovery. We ask that people respect her and her family's privacy at this time."
Last year (09), Chynna Phillips spoke out in support of her half-sister MACkenzie after the actress revealed she's had a decade-long sexual relationship with their father, Mamas & The Papas founder John Phillips.
In an interview with Oprah Winfrey, the singer said, "I was praying for her (MACkenzie) the whole time because it's a very, very taboo (subject). Many people were repulsed, many people were horrified at the allegations.
"I'm proud of my sister. Am I exceedingly joyful that my family secret that I told, maybe, my therapist, my husband and my very best friend in the world (is out)? No... it's very upsetting."
