Tonight Show With Jay Leno

If you insult Justin Bieber, you better believe his Beliebers will be after you! Olivia Wilde learned that the hard way when she tweeted that the 19-year-old pop star needed to "put a f---ing shirt on." Well, on Tuesday, Jason Sudeikis' fiance talked about her feud with the Biebs -- and the backlash from his fans! -- on the "Tonight Show with Jay Leno."

"This started because Justin Bieber went out without his shirt on...and he was in London, and it's so cold there and I was concerned," she said. "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. So I told Justin Bieber, 'Put your f--king shirt on.'"

Let's be nice to the Biebs. He's had a rough month so far!

"I said it with love!" the "Incredible Burt Wonderstone" star said with a smirk. She then quipped that "people misunderstood and thought it was mean-spirited. They didn't understand it was said with love!"

The 29-year-old actress "got a lot of interesting feedback from (Justin's) fans." Joking that she heard from "about 35 million (people)," Olivia read aloud some tweets directed toward her.

"One of them was, 'Are you a lesbian, or are you too old?' And it's great -- because it's a question I'd never asked myself before," she deadpanned. "And I was wondering, am I too old to be a lesbian?"

Another fan told Olivia to "Put your shirt over your mouth," which she plans to use as a "Shakespearean insult" later on.
