You know when you’re watching live TV or listening to callers on the radio, and they say or do something that forces you into a state of second-hand embarrassment? We felt that when we heard this recent radio interview with Justin Bieber.

The Canadian superstar called in to a Detroit-based radio show to talk about his latest album, Believe. The entire interview was all kinds of uncomfortable. First, the host of the show, Mojo, admitted that when he first heard Bieber’s track “Boyfriend,” he thought it sounded similar to Justin Timberlake. Though he meant it as a compliment, Bieber didn’t take it as one.

Then the interview took a particularly awkward turn when Mojo asked Bieber about his blooming friendship with boy band One Direction. There have been reports of band member Harry Styles dating older women, which Mojo referenced when he asked Bieber, “Do you worry about Harry being around your mom, since he likes older women?”

The question was repeated a second time to a less-than-impressed Bieber, who responded with “I think you should worry about me around your mom, bro.” When Mojo informed Bieber that his mother is dead, a few painful, silent seconds ticked by until Bieber finally hung up.

The singer’s PR people tried to blame poor reception for the lost call, but later admitted that he was upset by the question and wouldn’t be calling back.

While we think that both parties acted immaturely—making inappropriate comments about someone’s mother is never okay—we respect that Bieber stopped the interview after the tasteless mom reference.

What do you think of the interview? Did the radio host cross the line?
