Justin Bieber Attacked on Twitter by Olivia Wilde: 'House' Actress Tells the Biebs to Put His Shirt Back On

Remember that picture of a shirtless Justin Bieber in London? Well apparently not everyone was impressed with Bieber's shirtless antics. Actress Olivia Wilde doesn't want to see Bieber without a shirt again. @oliviawilde tweeted March 2 telling the singer to put his shirt back on.

Wilde tweeted, "Bieber, put your f---ing shirt on. (unless you lost all your shirts in a fire in which case my condolences and please purchase a new shirt.)"

Unfortunately for Wilde, she tweeted at the wrong celebrity. Bieber's fans have since come out in defense of Bieber and the name calling has gotten quite nasty. You can find the responses to Wilde's tweet here.

An incensed Bieber fan stuck up for the "Beauty And A Beat" singer by tweeting, "who are you again? huh? exactly."

Ouch! Wilde may be best known for her role in the hit TV show "House." She also has been in movies such "Tron: Legacy" and "The Change-Up." Wilde recently used Twitter for something a bit more positive when she announced she was engaged to SNL star Jason Sudekis.

While some of Bieber's fans didn't take too kindly to Wilde trying to tell Bieber what to do with his shirt, others enjoyed Wilde's tweet and got in on the fun.

One fan tweeted at Wilde, "if Bieber is wearing his overalls, does that count as a shirt? If there is nipple coverage he should be technically OK, right?"

No word yet if Bieber was upset at Wilde's dig on Twitter, but chances are the singer has bigger things going on then to worry about Wilde's tweet. However, Bieber's fans likely won't let Wilde forget about her mistake. You don't bash Bieber on Twitter!

Bieber fans do you have a problem with Wilde calling Bieber out on Twitter? Or do you agree with Wilde that Bieber needs to keep his shirt on, especially when he is walking outside in London?
