Walt Or Jesse? Monica Or Rachel? Watch Jess & Matt Take Our 'Awesome Twosome' Challenge

Can you ever truly know someone?

That's the question we put to X Factor stars and singing duo Jess & Matt... in the most frivolous way possible.

The two of them swung by Student Edge HQ to promote their new single "Bones", so we decided to test their relationship with our 'Awesome Twosome' Challenge (which is definitely a thing; or at least, it is now).

We put Jess & Matt in separate rooms and quizzed them on some famous duos, making them pick a favourite, and then seeing if their answers matched up.

Do they prefer Chandler or Joey? Are they bigger fans of Paul McCartney or John Lennon? Can they tell the difference between Mary-Kate and Ashley Olsen? Do they truly think as one? This video reveals all.
