Oprah’s really on her grind. She’s queen of interviewing those making a comeback: first Whitney, then Jay, now Mariah.

Earlier today, as a part of Oprah’s live Friday concert series, Mariah Carey took to the stage at Central Park and, backed by a chorus line – you know, Mariah loves a robed choir behind her – brought the house down by singing the new single from her upcoming album. “I Want To Know What Love Is”¬† was originally sung by the band Foreigner and released in 1984, but Mariah’s cover is just as good. She brought her hubby Nick Cannon along for the interview, their first together as a couple, and looked casually cute in an all-black form-fitting outfit. Check the curly hair, too – circa “Vision of Love.”

Watch Mariah perform her newest single (and Oprah make a wish come true for a few fans):

Watch the couple get candid about their relationship, the proposal and all!
