Celebuzz had to do a complete double take when we spotted this new image of Polish actress Kasia Smutniak from the 69th Venice International Film Festival on Sunday.

Is it just us, or is Smutniak Black Swan actress Natalie Portman‘s doppelgänger?

Both stars are strikingly beautiful yet they look freakishly similar.

And, they are not the only star “twins” in Tinseltown.

Who are other celebrity lookalikes?

At first glance, Modern Family‘s Sarah Hyland resembles a younger Mila Kunis – as the pair share those sultry eyes and perfect brunette manes.

Even actors who are best friends, like Twilight star Robert Pattinson and Sienna Miller‘s hubby Tom Sturridge, seem to mirror each other.
