Two very famous people singing together on their morning commute. Glorious.

How do you top Mariah Carey belting out karaoke in your car on the morning commute? By inviting Jennifer Hudson for a car-ride singalong, it seems.

Actor/comedian/singer James Corden just shared a car ride and a duet with none other than Oscar-winner Jennifer Hudson — and recorded the gloriously musical trip.

In his second excellent installment of Carpool Karaoke for The Late Late Show with James Corden (the first instalment involved Mariah singing Always be my Baby ), an impatient Corden waited in his car for Hudson, 33, to join him for his morning commute.

Then, during the trip to his LA studio, the pair duetted on her new single Trouble with rapper Iggy Azalea (he was a very able Iggy) and other songs from her back catalogue.

The ride included a musical stop at a drive-thru window (the word “cheeseburger” has never sounded so soulful).

Another highlight: 26-year-old Cordon nailed his R. Kelly impression while requesting a Diet Coke.

Hudson used to work at Burger King, and told Corden her favourite part of the job was singing to drive-thru customers.

(Imagine Jennifer Hudson sing-asking, ‘do you want fries with that?’)

Hudson and Gordon doing And I’m Telling You I’m Not Going from Dreamgirls was also flawless–  partly because Hudson exhorted her recorded self to “Sing, Jennifer!”

Cordon held his own against Hudson’s incredible voice, but became slightly carried away: He was so lost in the moment, Hudson had to remind him to put his hands back on the wheel.

Ah, bless.
