Justin Bieber ended a radio interview after the host made a joke about Harry Styles and the singer's mother.
In a recent interview with Mojo In The Morning, host Thomas Carballot asked the Boyfriend singer what he thought about Harry Style's relationship with older women.
Carballot said: "Do you worry about Harry around your mum, since he likes older women?"
Bieber asked the host to repeat the question, before replying: "I think you should worry about your mum, though."
When Carballot revealed that his mother was dead, Bieber hung up the phone.
Bieber's management admitted that he was "a little upset" by the question after attempts to reconnect the call failed, and said that he will "probably not" call the station back.
