Chynna Phillips, who entered rehab for anxiety over the weekend, is receiving lots of love and a vote of confidence from one of her closest friends, Wilson Phillips bandmate Carnie Wilson.

“She’s going to be fine,” Wilson, 41, tells The Insider. “Anyone that goes into rehab needs help. She knows how much I love her. She’s my lifelong friend and my oldest friend. I wish her all the best in her recovery.”

Asked if they will perform together anytime soon, Wilson says, “We will.”

Chynna Phillips, who turned 42 on Friday, is the half-sister of Mackenzie Phillips, who said last fall that she had once had a sexual relationship with their father.

Chynna was shaken by those claims, but a source said her decision to seek treatment was based on “a combination of things.”
