Olivia Wilde has been blasted by Justin Bieber's fans.

Devoted followers of the 19-year-old singer - who call themselves "Beliebers" - were outraged when the House actress took to Twitter to slate Justin for his love of walking around topless, after recent pictures emerged of him in London without a shirt.

"Bieber, put your f---ing shirt on (sic)," she wrote.

One fan tweeted, "justin probably doesn't even know who [footballer] joey barton or olivia wilde are LOL you guys just hate from the back." Another simply wrote, "@oliviawilde i'll punch you in your face (sic)."

Olivia is the latest high profile celebrity to hit out at Justin, after The Black Keys drummer Patrick Carney insinuated his music isn't good enough to win awards.
