“My whole life I was 106 pounds, and I haven’t been that in a million years,” she said. “I can’t really get into most of them. There’s a big difference between 106 and 126.”

She also has a surprising skin care routine.

“I have a friend, Dr. Barbara Sturm, and she makes an eye cream and face wash that I love,” Cher said. “I love Jan Marini products too. I also have Proactiv products that I love.”
