Mariah Carey tapes 'Carpool Karaoke' with James Corden

Mariah Carey was certainly up to something when she was spotted outside Lovi’s Delicatessen Restaurant.

She taped a Christmas edition of 'Carpool Karaoke' with James Corden in Calabasas, CA. With her festive concerts, and E! reality show lined for December, MC really is pulling out the stops to give lambs a Mimi-filled Christmas!
