Don't mess with a Belieber - or 35 million of them.
On the "Tonight Show with Jay Leno" on Tuesday night, Olivia Wilde talked about receiving a barrage of backlash spawned by her recent tweet poking fun at teen heartthrob Justin Bieber.
On March 1, Wilde riffed about Bieber being photographed without a shirt while in London, writing: "Bieber, put your f------ shirt on. (unless you lost all your shirts in a fire in which case my condolences and please purchase a new shirt.)"
The result? Tons of angry tweets, a few of which Wilde jokingly read out loud to Leno, including one that called her a "lesbian" and "old."
