Mariah Carey and Miguel Perform '#Beautiful' at Summer Jam XX

Miguel added some star power to his Summer Jam set by bringing out J. Cole and Mariah Carey. The R&B crooner and pop diva dueted on Mariah’s single “#Beautiful” at New Jersey’s MetLife Stadium on Sunday.

“I don’t think you know who this is ’cause if you did, you’d be making the loudest noise you could,” said Miguel before the pop diva strutted on stage in white cutoff shorts and a midriff-baring top with sparkly heels.

Mimi hit some glass-shattering high notes as Miguel crooned in his falsetto.
