Chynna Phillips Checks Into Rehab For Anxiety

Chynna Phillips, member of the 90's group Wilson Phillips, has "checked into an undisclosed treatment facility for anxiety," according to her rep, Lizzie Grubman.

Phillips, 42, has three children with her husband, actor Billy Baldwin. Grubman released a statement saying, "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."

Phillips' half-sister Mackenzie went public last fall, with accusations that their father provider her drugs and forced her into an incestuous relationship with him. The confession landed Chynna on Oprah to speak about the situation with her father, John Phillips, of the Mamas and the Papas. Phillips said, on the talk show, I pray that we all get closer through this crisis ... But I would be lying to you if I didn't tell you that there are going to be some huge obstacles in front of us."
