A fuming Justin Bieber hung up on a radio interview after a presenter asked him cheeky question about his mum and One Direction singer Harry Styles.
The Baby star already appeared to be offended in the interview after being compared to Justin Timberlake.
MOJO radio presenter Thomas Carballot said that "Boyfriend" sounded like a Justin Timberlake song.
Justin replied: “That’s crazy. Our voices sound nothing alike. Saying I sound like someone else is not really a compliment.”
But his nerves were lost when the DJ asked him if he worried about Harry Styles being around mum Patti, “since it seems he likes older women.”
He snapped back: “I think YOU should worry about me around your mom, bro.”
Then when the MOJO radio host replied that his mother was dead Justin hung up.
After the incident, 18 year old Justin’s management admitted the star was "a little upset" by the question.
