Mariah Carey helped kick off the ‘The Today Show’ Toyota Summer Concert Series this morning with a three song set. She started with her hit ‘Touch My Body’ and then called Wale to help debut ‘You Don’t Know What To Do’ from her upcoming album Me. I Am Mariah… The Elusive Chanteuse, hitting stores on May 27th. The song sounds groovy but Wale messed up little with his second verse. Watch the footage below.
