Currently taking a break from touring across the world, Justin Bieber has been hanging out with his wife, Hailey Bieber (Hailey Baldwin), trying to "self-improve" himself.
The might include taking up some MMA lessons or at least practising his ground game after the octagon. On Sunday night, Bieber sent out a random tweet, essentially challenging Tom Cruise to a fight inside the octagon while tagging UFC president Dana White.
