MUMBAI: Justin Bieber has been slammed by heavy metal fans for wearing a Metallica t-shirt.

Bieber’s fashion choice evidently rubbed a lot of people the wrong way as they mocked the hitmaker for his attire.

One user wrote: "Take that shirt off you don't deserve it."

While another added: "U r a disgrace to metallica."

Someone else stated: "I love Metallica and I hate Justin Bieber."

The ‘Beauty and a Beat’ singer is no stranger to online abuse, with his ‘Baby’ music video topping the list of most disliked YouTube clips of all time.
