There are countless lotions, potions and camera tricks to help Hollywood stars look their best. But not every celebrity has a personal spigot connected to the fountain of youth — and some stars wear the results of their hard-partying antics more than others. To mark Adele's 29th birthday on May 5, 2017, Wonderwall.com is taking a look at some of the stars you might not believe are actually the same age! Read on for more…

Jennifer Lawrence and Sarah Hyland
"The Hunger Games" lead Jennifer Lawrence and "Modern Family" actress Sarah Hyland are both '90s babies. Maybe it's because Sarah plays a teenager on "Modern Family," but we always thought she was younger!
Kate Winslet and Tara Reid
Oscar winner Kate Winslet is one of the classiest leading ladies in Hollywood, while Tara Reid is, well, Tara Reid. The "American Pie" star is only a month younger than the British actress, but her penchant for hard partying, heavy makeup and club-ready fashion certainly makes it seems like there would be an age gap between these two.
Ryan Reynolds and Blake Shelton
Gwen Stefani and Catherine Zeta-Jones
Apparently, No Doubt frontwoman Gwen Stefani is one of those stars with a personal spigot connected to the fountain of youth. Catherine Zeta-Jones is still one of the most beautiful women on the planet, but Gwen looks like she hasn't aged since the '90s.
Dakota Fanning and Courtney Stodden
Yikes! Courtney Stodden could be fresh-faced Dakota Fanning's mom — or at least her crazy aunt. But the teen bride-turned-reality star is actually six months younger than the "Twilight" actress.
Jake Gyllenhaal and Macaulay Culkin
Maybe it's just that Macaulay Culkin will always be the little kid from "Home Alone" to us — or that he still grows peach fuzz instead of a full beard — but we can hardly believe the former child star is four months older than Jake Gyllenhaal.
Sofia Vergara and Gabrielle Union
Penelope Cruz and Alyson Hannigan
These lovely actresses have plenty in common: They're both married to actors; they both have two children; and they both were born in 1974. And here we thought the "How I Met Your Mother" alum was still in her early 30s!
John Cho and Dwayne Johnson
Wait, John Cho is in his 40s? Wow! He's only a month younger than Dwayne Johnson, but the "Harold & Kumar" star looks like he's half The Rock's age, doncha think?
Stacy Keibler and Coco Austin
Good hair and makeup make all the difference! Stacy Keibler's natural look is just right for a woman her age, but Coco Austin looks a decade older thanks to her heavy makeup and platinum-blonde locks. It's like she's trying too hard to look young. Can you believe she's only seven months older than George Clooney's ex?
Scarlett Johansson and Avril Lavigne
Scarlett Johansson has been portraying characters older than her real age since she was a teenager — and Avril Lavigne, well, she's still singing about Hello Kitty. So maybe that's why we were shocked to learn that the Oscar nominee is actually two months younger than the pop star.
Nicolas Cage and Keanu Reeves
For two dudes who have both been accused of being immortal, it's pretty crazy that Nicolas Cage looks so much older than Keanu Reeves.
Selena Gomez and Kate Upton
Blonde bombshell Kate Upton found fame flaunting her famous figure for Sports Illustrated's Swimsuit Issue in 2011. Imagine our surprise when we realized she was just 18 at the time! Selena Gomez, who's only a month younger, was still working for Disney at that age.
Snooki and Blake Lively
Nicole "Snooki" Polizzi will always be 21 in our hearts and minds thanks to her stint on "Jersey Shore." Even now that the hot mama has started acting her age, we're struggling to accept that she's only three months younger than "Gossip Girl" alum Blake Lively, whose maturity makes her seem years older.
Chris Colfer and Alex Pettyfer
We'd still buy that baby-faced "Glee" star Chris Colfer is a high school student. But with his chiseled jawline and 5 o'clock shadow, Alex Pettyfer could pass for a full decade older. (He's actually only a month older than Chris!)
Selma Blair and Carmen Electra
When did Selma Blair grow up? It's hard to believe the "Cruel Intentions" star is already technically middle-aged. She looks years younger than Carmen Electra, who is only two months older.
Lady Gaga and Lea Michele
Anne Hathaway and Gillian Jacobs
"Colossal" actress Anne Hathaway and "Love" star Gillian Jacobs were both born in 1982. Anne's refined style in contrast with Gillian's soft, quirky fashion sense suggest there's a bigger age gap than you might think!
