Beckinsale is known for being outspoken, and recently responded after a fan suggested she had a facelift.

“no threads no thread lift no Botox no laser no nose job no filler,” the actress wrote. “I do have facials with prp to boost collagen and micro current for skin tightening and oxygen. I probably would try laser but I’m a bit scared. Haven’t so far.”

Beckinsale gradually began acting. Both of her parents, Judy Loe and Richard Beckinsale, also were actors, with each appearing in British TV shows. Beckinsale’s big break came with a role in the World War II film, “One Against the Wind.”
