With James Corden as host, this was both expected and essential...
Last night at the 59th GRAMMY Awards, James Corden did a live carpool karaoke with JLo as the passenger.
John Legend, Jason Derulo and Keith Urban also joined in a sing-along for their rendition of 'Sweet Caroline.'
Watch out Beyoncé - it won't be long before Blue Ivy is challenging you in the charts. She ran over to James during the middle of it and got the mic.
