Chynna Phillips has checked into rehab, her good friend Owen Elliot has confirmed to RadarOnline.com.
“I won’t comment on the reasons why she’s there, but I love her and she has my undying love, support and confidentiality,” Elliot said. Elliot is the daughter of the late Mama Cass Elliot of the Mamas and the Papas and is a childhood friend of Chynna’s.
Chynna checked herself in over the weekend for “anxiety” her rep said. She is the half-sister of Mackenzie Phillips, who released a book last year detailing her rape by and sexually abusive relationship with her father “Papa” John Phillips.
Chynna is married to Billy Baldwin and released an album, One Reason, with Vaughn Penn in 2009.
