Mariah Carey kept it festive while kicking off the TODAY Show's summer concert series this morning (May 16), bringing her hits, both new and old, to 30 Rock. After performing "Touch My Body" and "Always Be My Baby", Mimi also debuted a new song off her forthcoming LP Me. I Am Mariah... The Elusive Chanteuse called "You Don't Know What To Do", alongside rapper Wale. This marks Mrs. Cannon's second rap track this week after giving Revolt the green light to drop the Rich Homie Quan-assisted "Thirsty."
