Justin Bieber's Carpool Karaoke segments have been incredibly popular online, with each one racking up millions of views on YouTube, and host James Corden has spoken out about getting him involved in the feature. 

Corden told Britain's Heat magazine that his bond with the Canadian sensation grew as a result of having him on the show and he's glad to see that Bieber's Carpool Karaoke clips have helped to change his public image:

"It's been so great to form a wonderful working relationship with him. It's a two-way partnership built on respect. It's very flattering to see him talking about us in interviews and saying that him doing Carpool Karaoke has helped change the public perception of him."

Corden has enjoyed phenomenal success with the entertaining segment, but confessed that the quality of the clips produced so far has meant that there's more pressure to do better every time they make a new one: "The best and worst thing is that there's another one the next day. When you do one that's great, it's almost harder, as you think, 'We have to do one as good as that tomorrow.'"
