There seems to be a bit of confusion of late.
To clarify: This is Scarlett Johansson. This is Amber Heard. However, it would seem The New York Post and The Metro Herald thinks they are the same person.
The New York post reported this story yesterday with this picture of Amber Heard. This morning, the Metro Herald followed suit.
Scarlett, as this story points out, likes boys - namely "advertising executive Nate Naylor". She has had a number of high profile unions, like with Sean Penn and Benecio Del Toro. She was also married to Ryan Reynolds for a while. She had her phone hacked and we saw her bits.
Amber Heard, as this story highlights, prefers girls. She's also been in considerably less films than Scarlett Johansson.
They've shared a hairstyle a few times. That is all.
