A few weeks ago, the Biebs was seen walking around (cold) London without a shirt, and out of concern for the 19-year-old, Olivia 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.)"

Oh no she didn't.

Needless to say, Wilde was then inundated with "35 million" tweets from furious fans ... and they're hysterical.

Watch the video below to see Olivia recount the story and read some of the Belieber responses, including name calling and asking if she's a lesbian....wow, really?!?
