Hollywood magic can definitely mask the ages of its stars. But sometimes, the celebrities do it themselves -- through the roles they play, the things they do, or just their overall look. Take a look at these stars whose ages we think are mysteries.
Taylor Swift
Real Age: 19
Our Age: 14
The country cutie just doesn't seem old enough to vote to us.
Ellen Pompeo
Real Age: 40
Our Age: 30
She's only a resident on 'Grey's,' so we can't believe Ellen is actually 40.
Cory Montieth
Real Age: 27
Our Age: 17
It's not just because Cory plays a high school student that we think he still could be in his teens.
Lady Gaga
Real Age: 23
Our Age: 33
Gaga fans, don't freak out. We don't think she looks old, it's just that her body of work makes her seem more mature than a girl in her early twenties.
Angelina Jolie
Real Age: 34
Our Age: 45
Just like Lady Gaga, everything Angelina Jolie has done -- including being a mother of six and an Oscar win -- elevates her age in our minds.
Keiko Agena
Real Age: 36
Our Age: 15
Seriously, the 'Gilmore Girls' star does not look like she's really older than Angelina, does she?
LeBron James
Real Age: 24
Our Age: 34
The reigning NBA MVP is worth millions of dollars, has an Olympic gold medal, took the Cleveland Cavaliers to the finals in 2007 and has broken league records left and right at the ripe old age of 24. We don't believe it.
Miley Cyrus
Real Age: 16
Our Age: 27
With the skimpy outfits and the pole dancing, the teen queen is more Britney than Disney innocent.
Olivia Wilde
Real Age: 25
Our Age: 35
She's not old enough to be a doctor if she wanted to be (unless we're talking Doogie, here). But it's Ms. Wilde's elegance that adds to her number.
John Francis Daly
Real Age: 24
Our Age: 14
Maybe it's because we can't get 'Freaks and Geeks' out of our minds, but Daly doesn't look a day over 14.
Gabrielle Union
Real Age: 37
Our Age: 16
We were absolutely shocked when we saw Union's birthdate. Shocked.
