Hanson have compared Justin Bieber's music to a sexually transmitted disease.
The pop trio - made up of brothers Isaac, Taylor and Zac Hanson - are clearly not fans of the 23-year-old pop superstar's music and when they were asked to identify his latest single 'Despacito' in a game of 'Whose Song Is It Anyway?' things took a turn for the worse.
Appearing on Australia's Hit107 FM, Zac confessed:
"Can I just say I'm glad I didn't know what that was?
"I prefer not to get any venereal diseases, whenever Justin Bieber gets sort of near me or near my ears ... I'm [out.]"
The 31-year-old star slammed the 'Sorry' hitmaker's songs saying they are "terrible" and listening to them is like having an "ear infection".
While one of his brother's took it a step further labelling his tunes "chlamydia of the ear".
They added: "It's chlamydia of the ear. It sucks."
Justin has had a hard time of late after getting a water bottle thrown at him on stage at Summerburst Festival in Stockholm, when he confessed he "didn't know" the Spanish lyrics to 'Despacito'.
And at a recent performance in New York, the hunk changed the word Despacito to "Dorito".
He sang: "I don't know the words so I say 'Dorito' / I don't know the words so I say 'Dorito' / I don't know the words so I say 'Dorito' / Despacito/ I ate a burrito / I just want a burrito."
However, his collaborator on the chart-topper, Luis Fonsi, has defended Justin for not picking up the lyrics in the language.
He recently said: "I don't blame him not knowing [the lyrics], and I think we have to give him a little bit of a pass because that's not his main language ... We can't expect the guy to just out of the blue get it perfectly."
