Justin Bieber walks out on radio interview

Justin Bieber walked off a Spanish radio chat on Wednesday (28Oct15) as the show hosts attempted to record a "break the Internet" stunt.

Nine minutes into his interview on 40 Principales, Bieber agreed to take part in the publicity grabbing stunt - and then simply left the studio and didn't return.

It's not clear what irked the Baby singer, who had previously answered quirky questions about his regrets and clothing choices - and when the hosts asked him to help them "break the Internet" by making a viral video, he initially said, "Let's do it".
