The Gossip Girl hottie looks like a slightly-cuter version of Lost actor Ian...From the dark, messy hair to the slight facial hair and clear blue eyes, they really do look like twins. They are almost identical in suits! And who wouldn’t want twins as hot as these two?!

Katy’s wide eyes and cute, cheeky smile makes her look exactly like Zooey...Even their dark chocolate hair is the same! They both have fantastic singing and acting skills, too, and their laughs are even quite similar...these two could fool anyone!

3. Kiera Knightley and Natalie Portman

From their delicate, porcelain skin to their fresh faces and shiny, almond eyes, these two could be the most stunning sisters in the world. Seriously, find good pictures of the two, and you won’t be able to tell which one is which! I’d love to be the third sister of these...aren’t they just gorgeous?!

4. America Ferrara and Jordin Sparks

Anything but ugly, the Ugly Betty star America has so much in common with singer Jordin Sparks. They both have the same luschious, bouncy hair, gorgeous lips and shiny eyes...they even look great in the same styles.

Imagine Robbie younger, and with less hair, and you’ve got hot new Glee star Mark. Not only can Mark do the badboy look exactly like his older look-a-like, but he pulls off the same cheeky boy look, too, and he certainly has the voice. Well, I wouldn’t mind an older brother like Robbie!

6. Gemma Ward and Sasha Pivovarova

Australian model Gemma has the innocent, natural look down to a T...from her always-sexily-messy blonde hair to her large blue eyes and defined cheek bones, and Russian model Sasha is almost identical. They even model the same clothing!!

7. Selma Blair and Michelle Monaghan

Selma is gorgeous...despite being quite pale she pulls off her striking dark hair and heavy fringe perfectly, and it really makes her glow. The only difference between her and Michelle is Michelle’s slightly lighter hair, and different fringe. Otherwise, the two have very similar facial features, and even similar bodies. And they are both totally gorgeous!

8. Mila Kunis and Vanessa Hudgens

Both Vanessa and Mila do everyday glamour effortlessly, with their glossy black hair, loose volume and pretty eyes. They both look great with make up or without, and they both have the exact same sultry stare...and of course, they are both very hot.

How similar do these celebs look!? I couldn’t believe that they aren’t actually related...I mean, imagine meeting someone who looks just like you? Crazy! They are all totally gorgeous, though, and I’d love to be part of any of these fictional families. Have you spotted a pair who must have been separated at birth? I’d love to hear about it!
