Susan Sarandon's just the kind of "cool girl" star who can rock attitude-packed sunglasses on the red carpet. The actor turns 70 this year, although you'd never guess it. Like Helen Mirren, she's got an ambassadorship with L'Oreal, and it's a responsibility she takes seriously. On the topic of the company's "anti-aging" products, she expounded "Aging is a good thing. I think it means staying healthy. I think there's something about not giving up and becoming invisible, which is what our society has a tendency to do. I hear women [of a certain age] talking about becoming invisible. My interpretation of anti-aging means anti-becoming invisible" in an interview with Refinery 29.

From a karate-chopping, catsuit-wearing spy in the 1960s TV program "The Avengers" to name-taking matriarch Lady Olenna Tyrell on "Game of Thrones," it's quite clear that Dame Diana Rigg has chutzpah in spades. She's aged incredibly over her decades-long career, and serves as amazing inspiration for all who are fortunate enough to watch her kick-ass performances.

After completely reinventing/reinvigorating the wrap dress, Diane von Furstenberg has only continued to grow her fashion empire over the years. She admitted to E! News that aging definitely takes its toll -- as she explained, seeing herself on the big screen "with no plastic surgery at my age, it's not the easiest thing." Still though, the iconic fashion designer remains stylishly ageless as she keeps maintaining her status as a major influencer. Plus, she waxed poetic on the topic in her memoir, "The Woman I Wanted to Be" when she said, "There is a saying that with age, you look outside what you are inside. If you are someone who never smiles your face gets saggy. If you're a person who smiles a lot, you will have more smile lines. Your wrinkles reflect the roads you have taken; they form the map of your life."

Credited as a pioneer for female comedians, Lily Tomlin has managed to break the glass ceiling in a major way -- and she's still going strong at 77. The "Grace and Frankie" star and her co-star Jane Fonda recently joked about aging at the Television Critics Association's winter press tour, where she noted "denial" as a key component of aging gracefully. Honestly, if Lily Tomlin says denial is the way to go, we might just have to give it a try.

Can you believe this "Shakespeare in Love" actor turned 80 back in 2014? You'd never guess it, neither from her sprightly appearance, nor from her powerhouse performances. Over the years, she's played such iconic roles like Queen Elizabeth, James Bond's M, and (our personal favorite) Lady Catherine de Bourgh -- and she's got just as much attitude as her most famous characters. She joked to People Magazine about aging, saying, "There's nothing good about being my age... Someone said to me, 'You have such a wealth of knowledge,' and I just said 'I'd rather be young and know nothing, actually.' Bugger the wealth of knowledge."
