Shania Twain will be 50 in August, so that qualifies her to discuss whether or not women of a certain age are allowed to be sexy, right? That's what Canada's "Maclean's" magazine thinks.

They asked for her take on 56-year-old Madonna getting criticized for her sexed-up performance at the Grammys. Naturally, she thinks it's unfair.

Twain says of the criticism on sexiness at a certain age: "It's like saying once you reach 70, you should stop having sex. Art is a platform where self-expression should not be limited. There's no age limit to that."
