15 Celebrities Who Are Way Older Than You Realized

Hollywood stars are well-known for being beautiful, but some seem like they never age a day. True, some celebrities lie about their age, whether to be considered for more parts or to avoid the additional criticism from the public. But these famous people aren't lying about their ages – they're just further on in years than you probably assumed.

Some celebrities who are older than you thought are perennially baby-faced. Jack McBrayaer, AKA Kenneth the Page from 30 Rock, and former That '70s Show star Topher Grace spring to mind. Others became famous for their obsession with stereotypically youthful topics – Chris Hardwick, anyone? And then there are the timeless stunners, like Helen Mirren and John Stamos. Generations have shared crushes on the surprisingly mature celebrities.

Aging isn't always pretty, but let these stars who are way older than you realized inspire you. Who says getting older has to be a bad thing?

Eternally youthful comedian Chris Hardwick was born in 1971, but doesn't look it. An occasional actor, host and presenter, Hardwick might be best known for hosting @Midnight, a game show on Comedy Central. People might also think he's super-young because he's married to heiress Lydia Hearst, who's 13 years his junior.

Elijah Wood – best known as Frodo Baggins in the Lord of the Rings movie trilogy – apparently never ages, though he was born in 1981. Just like Frodo went on his journey to Mordor, Wood has gone on an entertainment odyssey as well. He's started his own record label, become a DJ, voiced cartoon characters, and starred in many a quirky TV show.

A-list actress Gabrielle Union, born in 1972, looks just as stunningly youthful now as she did in 2000's Bring It On. The star of BET's hit Being Mary Jane is also known for her high-profile marriage to NBA superstar Dwyane Wade. Union credits drinking water and using oil-based beauty products for keeping her looking sprightly.

Born in 1969, Gwen Stefani continues to rock on like someone 30 years her junior. The former No Doubt frontwoman stuns with her signature bleached blonde hair and red lip on The Voice. She is also dating a younger man, singer Blake Shelton.

Born in 1970, Heather Graham doesn't seem to have aged a day since she starred in Austin Powers: The Spy Who Shagged Me in 1999. The Twin Peaks alumna is also well-known for her roles in The Hangover and Boogie Nights. In particular, she credits getting 11 or 12 hours of sleep per night for her youthful appearance.

Jack McBrayer, born in 1973, played ageless page Kenneth Parcell on 30 Rock. The Second City alum has also guested on just about every comedy series under the sun, and has done tons of voiceover roles, too. His Southern accent and goofy sweetness are the hallmarks of his work.

John Stamos, born in 1963, is just as handsome now as when he was Uncle Jesse on Full House. His TV career continued and he even made a Broadway debut. Stamos famously married and divorced supermodel Rebecca Romijn before becoming a perennial bachelor.

Born in 1964, Keanu Reeves must have gotten stuck in The Matrix, since he looks the same now as he did when starring in that hit franchise. The motorcycle-riding chameleon morphs from one role to another, but he is best known for his roles in action franchises. His timeless looks have even inspired fan devotion on sites like KeanuIsImmortal.com.

Hip-hop megastar-turned-movie star-turned-TV star LL Cool J doesn't seem to age, even though he was born in 1968. The Grammy Award-winning artist behind hits like "Mama Said Knock You Out," "Doin' It," and "I Can't Live Without My Radio," has remained a perennial presence in entertainment for more than three decades. He's also starred in tons of movies – S.W.A.T. and Any Given Sunday, anyone? – and currently stars in the smash hit TV show NCIS: LA (and hosts Lip Sync Battle).

Topher Grace might have gotten married and started a family, but he'll always be cherub-faced teen Eric Forman from That '70s Show to fans. Although he ducked out of the series before it ended, Grace (who was born in 1978) is hoping for '70s to make a comeback. Mainly he wants to hang out with his former castmates – including Wilmer Valderrama, Ashton Kutcher, and Mila Kunis.
