As Carnie Wilson mulled over whether to undergo the Lap-Band procedure, she was afraid to tell sister Wendy Wilson and best friend Chynna Phillips.
“It’s not like me to hide things, but I’m in quite a bit of fear about this,” Carnie, 43, says on her TV Guide Network reality series taped before she had the January surgery. “That’s really the reason why I’ve put this off, not telling Wendy and Chynna. Something has to be done.”
Sitting in between her Wilson Phillips Still Holding On costars and former band mates at lunch, Carnie says, “I want to tell you guys something. I am going to have another type of weight-loss surgery that is going to help me.”
