And it'll clearly be short term if they're paying him more than Celine. Vegas is different because you get paid more than you gross since your fans are supposed to fly in, stay in your official hotel, buy your merchandise, eat at your restaurant, etc. Licensing is where the money comes from in Vegas and I don't see Bruno Mars pulling that off since he resonates more with the GP than he does with a solid fanbase.
Most girls can't even manage that on tour 
This is just additional coins.
