After Justin Bieber's random tweet challenging Tom Cruise to a fight at the Octagon - Dom came up with the Bieber battle game.
Justin Bieber is 25, Tom Cruise is 56 - the age gap is 31 years.
Take your name, add 31 years then Google a celebrity with that age to see who would battle you.
For Meg that was Nigella Lawson. She recently took a self defence class, so she definitely wasn't afraid to pick a fight... 😂
