These Stars' Real Ages Will Blow Your Mind

You know what's really under Pharrell's giant hat? Antiaging secrets. Seriously, this guy looks amazing. Thanks to his youthful style and fun-loving attitude, Pharrell manages to fool all of us when it comes to his real age — which is 42.

As one of rock's golden couples, Gwen Stefani and Gavin Rossdale seem to stay effortlessly young just by being ridiculously cool — running after two (soon to be three) boys might help, too. Gwen, who we all remember from the early days of No Doubt, looks incredible at 45, while 49-year-old Gavin still looks just as hot as he did on all those Bush CD covers from the '90s.

Something about Amber Heard reads older than her 29 years. She comes across as very mature and "together" in her interviews, and carries herself with poise on the red carpet. Her old soul may be why she's such a great fit for fiancé Johnny Depp, who recently turned 51.

Much has been made of Lorde's recent success — which includes a hit album and two Grammy wins — and the world has been collectively freaking out about the fact that she's only 18. Last year, her birth certificate was made public in order to prove that she is, in fact, a teenager. Take that, truthers!

Ah, Leo — it's like all the models, yachts, and newsboy caps keep him young or something. We all grew up with Leonardo DiCaprio and couldn't contain our love for him when he starred in classics like Romeo + Juliet and Titanic. So when the actor turned 40 recently, we couldn't help but be faced with the fact that we, too, are not starry-eyed teens anymore. Sigh.

Leo's Wolf of Wall Street costar Margot Robbie has quickly risen to fame thanks to her spot-on performance as Naomi in the Oscar-nominated 2013 flick. Thanks to her staggering good looks, charm, and poise, we consistently need to keep reminding ourselves that this Aussie newcomer is only 24.

Whether she's kicking ass in Charlie's Angels or solving crimes on Elementary, Lucy Liu has a way of making us think that she's much younger than her 46 years.

Are you ready for this? Jane Fonda is 77. We'll wait for you to pick your jaw up off the floor.

In addition to his amazing performance in Dallas Buyers Club, last year's award-season darling Jared Leto is also getting noticed for his perfectly tousled locks and slightly creepy inability to age. We're actually starting to wonder if Jared's a pod person, because he looks almost exactly like he did back in 1994.

Maybe it's her constant transformation for her movie roles or just that sophisticated British accent, but Kate Winslet always strikes us as older than her 39 years.

Adele is so gorgeous, talented, and accomplished that it always blows our minds when we realize that she's only 27 years old.

We had such a hard time accepting that Gabrielle Union is 42 years old that we had to dedicate an entire feature to it. Honestly though, what is this sorcery?

Perhaps it's the daily dance breaks that keep 57-year-old Ellen DeGeneres looking so spry!

Besides being one of America's fantasy best friends, 49-year-old Sandra Bullock just reads as completely ageless. From her roles in Speed and Miss Congeniality right up to recent performances in The Blind Side and Gravity, Sandra seems to have found the fountain of youth and eternal success.

We have yet to fully accept the idea that Eminem — aka Marshall Mathers, aka B. Rabbit, aka Slim Shady — is 42. It just seems wrong.

Talk about aging gracefully; everyone's favorite domestic diva Martha Stewart is 73.

During his 2014 Super Bowl Halftime Show gig, Anthony Kiedis surprised everybody by hitting the stage shirtless in 40-degree weather. After that shock wore off, people couldn't stop talking about how amazing the Red Hot Chili Peppers frontman looks at the age of 52. He's still got it, right?

Would you believe us if we told you that the stunning Salma Hayek is 48? Because she is. Just let it sink in.

It took us a while to fully comprehend the idea that James Lipton, drama school dean and host of Inside the Actors Studio, is actually 88 years old. James was also a pimp back in the 1950s, so there's a lot here to be confused about.
