We are on to Hollywood's secret -- Lala land knows the fountain of youth's location.
From performers pushing 50 without a gray hair in sight to celebrity adults convincingly playing acne-prone students, age truly ain't nothing but a number.
Don't believe us? Several stars look years younger than their birthday candle count. Check out these famous fresh faces seemingly stuck in adolescence.
It's no wonder Andrew Garfield played a teenage Peter Parker in <a href="http://www.huffingtonpost.com/2013/07/20/andrew-garfield-the-amazing-spider-man-2_n_3626424.html" target="_blank">"The Amazing Spider-Man."</a> The dapper 30-year-old could easily pass for a boy half his age!
Although <a href="http://www.huffingtonpost.com/2013/07/22/selena-gomez-birthday-video_n_3636274.html" target="_blank">Selena Gomez recently turned 21</a>, we think the Disney star resembles her tween Selenators more than an adult.
The majority of Gabriel Mann's "Revenge" co-stars are in their 20s, so we assumed he was too. It turns out he is <strong>double </strong>their age. The former model and actor is 41!
Need we explain? That face says it all. 21-year-old Logan Lerman's doe eyes remind us of junior high heartbreakers.
This <a href="http://videos.huffingtonpost.com/entertainment/20-questions-with-pretty-little-liars-star-lucy-hale-517172273" target="_blank">"Pretty Little Liars" star</a> looks little to us. Lucy Hale, 24, easily rocks the high school role -- her youthful appearance can't hurt with convincing either!
Dev Patel stole our hearts with "Slumdog Millionaire" and "The Newsroom." The 23-year-old's boyish good looks might be to blame. Or is it his accent?
The "Smallville" star's baby blues and rosy cheeks are adorably childlike. There's no way Tom Welling is 36!
M.I.A. definitely has a playful side with <a href="http://www.huffingtonpost.com/2012/02/05/mia-flips-bird-super-bowl-middle-finger_n_1256338.html" target="_blank">her rebellious onstage antics.</a> Now get this -- the rapper is 38 years old! She brings the house down better than female MCs half her age. Get it girl.
Bruno Mars radiates youthfulness at 27. Don't believe us? <a href="http://www.huffingtonpost.com/2012/12/09/bruno-mars-covers-part-of_n_2267725.html" target="_blank">He sings Disney songs</a> for goodness sake! Bruno could easily be mistaken for someone a decade younger.
Obviously, <a href="http://www.huffingtonpost.co.uk/2013/08/19/one-direction-harry-styles-this-is-us-documentary-press-conference_n_3778795.html" target="_blank">Harry Styles</a> had to be a boy band member. We actually believe the description since he looks more preteen than 19.
Lily Collins tries to appear older with her <a href="http://www.huffingtonpost.com/2013/08/20/lily-collins-abs-crop-top_n_3784395.html" target="_blank">crop tops</a> and <a href="http://www.huffingtonpost.com/2013/06/17/mortal-instruments-city-of-bones-new-trailer_n_3456333.html" target="_blank">edgy film roles.</a> Nice try but girl's still got the ultimate baby face. The 24-year-old looks <em>so</em> young.
24-year-old Chord Overstreet definitely fits the bill as high schooler <a href="http://www.huffingtonpost.com/2012/11/04/glee-wedding-ryan-murphy-hints-season-4-event-photo_n_2073150.html?utm_hp_ref=chord-overstreet" target="_blank">Sam Evans on "Glee."</a>
Our beloved Gilmore girl is ageless. Alexis Bledel may be 31 but she will always look like teenage Rory in our eyes.
Don't you just want to pinch Tom Felton's cheeks? The boyishly handsome villain grew up onscreen in the "Harry Potter" films. He is now 25.
Did you know someone put a ring on "Spy Kids" star Alexa Vega? The <a href="http://videos.huffingtonpost.com/entertainment/spy-kids-alexa-vega-all-grown-up-wearing-metal-bra-517885953" target="_blank">24-year-old </a>was married for two years to film producer Simon Covel.
So "Third Rock From The Sun's" Tommy Solomon is 32. WHAT? Joseph Gordon-Levitt will always be a child star to us. And we're okay with that.
22-year-old "Modern Family" star Sarah Hyland has that teenage touch. She could easily fit in with her fictional high school classmates.
Chace Crawford's "Gossip Girl" days are long gone, but his adolescent face still reads teenager even at 28.
Similar to her "Never Let Me Go" co-star Andrew Garfield, Carey Mulligan has a much younger appearance than her 28 years.
