"Since we used to be covered in hair, and now we're not except for a few places, I figure there's a purpose for that hair," the 41-year-old told the TV host.

"So I put some of the purposes for it and I also suggest that no matter how you enjoy grooming it throughout your life - whether it's shave it all off, wax it all off, put a bull's-eye, birthday cake, I don't care - just, girls, think about not taking it all off forever."
