After a tumultuous time during which she was treated for anxiety, Chynna Phillips is reuniting with Carnie and Wendy Wilson to kick off a new tour as Wilson Phillips and record their first-ever Christmas album.
“I’m thrilled that the Wilson Phillips family is coming back together again,” says Phillips, 42, who entered a treatment facility for anxiety in February, five months after her half-sister Mackenzie Phillips claimed she had a sexual relationship with their father.
“We’ve known each other for more than 20 years,” Chynna says of her bandmates. “We’re like family. I’m excited about working with the Wilson sisters again.”
