WATCH: James Corden gives Ariana Grande a piggyback ride in new Carpool Karaoke video

Cape Town - Pop star Ariana Grande joined James Corden for Carpool Karaoke and sang some of her biggest hits.

The video was released on Thursday and features the pair harmonising while singing Ariana's God is a Woman, Dangerous Woman, Side to Side, and No Tears Left to Cry.

The British host also took some time to clear up persistent rumours about the recently engaged star. 

At one point in the clip James and Ariana stopped to get some coffee and the singer got the talk show host to carry her on his back.
