Hell hath no fury like a Belieber scorned!

Actress Olivia Wilde found that out the hard way after she chastised Justin Bieber on Twitter for going shirtless in London.

That one comment sparked an all-out Twitter war and even Wilde was shocked by the onslaught.

During an appearance on The Tonight Show with Jay Leno, she laughed off the incident.

“You know, I have a 19-year-old brother in London and it’s freezing and if I saw him without a shirt, I would tell him to put it on,” she explained. “So I told Justin Bieber, put your f**king shirt on! With love! I said it with love.”

Wilde then proceeded to read off some of the hate tweets, which had the studio audience in stitches.
