Everyone has said at one point in their life “I wonder if there’s someone out there who looks exactly like me?” If you’ve never encountered your own doppelganger out there, take a look at these pairs of celebrity look alikes and have hope that your personal doppelganger is out there too.

1. Jimmy Fallon and Josh Radnor

Not only can they make people laugh with their comedy-- Fallon as the host of "The Tonight Show" and Radnor as the star of "How I Met Your Mother"--but these two have similar features that makes them twice as lovable.

2. Katy Perry and Zooey Deschanel

Both the pop singer and "New Girl" actress often get mistaken for each other, making us wonder if they happen to be long-lost twins.

3. David Beckham and Liam Payne

There is good news for One Direction fans who fear the band's days are over: it appears Liam Payne is bound to get even better with age, noting his uncanny resemblance to athlete turned model David Beckham. Bonus points for them both being British.

4. Aaron Rodgers and Jake Gyllenhaal

These men not only look oddly alike, but they are both accomplished in their professions: Green Bay Packers quarterback Rodgers has been named Superbowl MVP and Gyllenhaal has been nominated for numerous awards for his acting.

5. Bob Saget and Stephen Colbert

These comedians have more in common than their ability to make people laugh. Their resemblance is uncanny.

6. Kris Kristofferson and Jeff Bridges

There's almost no telling these two apart, as both the singer and actor sport facial hair and long gray locks.

7. Ian Somerhalder and Rob Lowe

Another pairing that you'd barely believe are separated by twenty years, these attractive actors would fool anyone into thinking they were brothers.

8. Jeffrey Dean Morgan and Javier Bardem

It's shocking that these two actors haven't been cast to play identical twins in a movie yet.

9. Harry Styles and young Mick Jagger

The second One Direction member to make this list, Harry Styles has plenty in common with Mick Jagger: they're both members of beloved bands, hail from England, and sported long, voluminous locks as young men.

10. Colin O'Donoghue, Novak Djokovic, and Adam Levine

The final spot on this list is a three way tie between O'Donoghue (otherwise known as Captain Hook on "Once Upon a Time"), tennis champion Djokovic, and Maroon 5 frontman Adam Levine. With dark scruff and brooding looks, this trio of look alikes can make any girl swoon.
