90's Celebrities: Past and Present

Alyson Hannigan

Hannigan's early career didn't feature any remarkable roles until her breakthrough in Buffy. From there, her career skyrocketed. She's widely recognized for her roles in the American Pie movie series and her iconic portrayal of Lily in the popular sitcom How I Met Your Mother.

Currently, fans can catch Hannigan hosting Penn & Teller: Fool Us, and there are rumors of her voicing Kim Possible's mother. Happily married to her Buffy co-star, Alexis Denisof, she's also a loving mother to two daughters.
