Gwyneth Paltrow has explained why Brad Pitt looks like his girlfriends

And it's amazing.

The Brad Pitt girlfriend theory is one of our favourite things to ever happen, with the internet noticing the hilarious link between the Fight Club actor and his exes last year.

The theory, that sees Brad changing his look to resemble the woman he is dating, went viral after his split from Angelina Jolie, due to the internet rehashing his previous relationships.

This of course dubbed Brad as ‘the man who likes to look like his girlfriends’, and after looking at the viral side-by-side photographs of the actor and his former flames, we get it.

When he was with Angelina Jolie, he went for slicked black hair and shades. Jennifer Aniston? Long blonde beach waves. And Gwyneth Paltrow? An actual blonde pixie cut with a side fringe.

And it didn’t stop there, with more photographs surfacing of Brad looking identical to other former girlfriends, Christina Applegate, Juliette Lewis, Geena Davis and Thandie Newton, back in the day.

This is truly the gift that keeps on giving. pic.twitter.com/XxnQgglkAq

How did we not notice this before?

While the images and theory went viral, neither Brad nor his exes made a comment, that is until now.

And who was it? Gwyneth Paltrow.

The 46-year-old actress and Goop founder took to Instagram to voice her thoughts on the theory, commenting on a fashion blogger’s Instagram of a newspaper article, entitled: ‘Brad: The man who likes to look like his girlfriends’.

Keeping her comment simple, she posted: ‘Or we like to look like him, let’s face it.’

This is hilarious.

But seriously, why do Brad and his exes look identical?
