Cobie Smulders

Remember that ’80s pop hit “Let’s Go to the Mall” from How I Met Your Mother? It was sung by character Robin “Sparkles” Scherbatsky, played by Smulders, 35, who—a decade ago—was diagnosed with ovarian cancer, which usually strikes women in their sixties and older. She beat it with multiple surgeries and held on to her fertility, reports Self. "Thankfully, gratefully, cancer did not get the best of me," Smulders wrote last year in Lenny Letter. “The best of me now lives on in my two little women, baby girls I was lucky enough to be able to make with my own body.”
