Justin Bieber may have had a pretty lousy birthday, but one of his Twitter followers is having a really lousy month — and it's all because of him.

About a month ago, Bieber decided to randomly retweet a random teenager's random review of his recently released acoustic album.

"Not really a fan of Justin Bieber but his acoustic album is actually good," tweeted 15-year-old Courtney Barrasford of Portsmouth, Hampshire.

"It wasn't too bad at first," Courtney told The Sun. "Some people were saying I was lucky I was retweeted by him and some were jealous."

But jealousy quickly gave way to rage as hundreds of Beliebers began inundating Courtney with death threats.

"I am a Belieber of him since 2009 and he didn't notice me," blubbered one Belieber. "And you're not even a fucking fan. You get noticed. OMG."

"Jus tell her to die...and leave Justin alone!" bemoaned another true fan.

Eventually, demands that Courtney kill herself gave way to a rumor that she was secretly pregnant with Bieber's love child. Courtney said that got to her more than any other comments.

"They started saying I was pregnant with his child, and that my child would be a prostitute," she told a local paper.

Courtney's mother Tina called the whole thing "silly," but also said it should be taken seriously. "I wonder if the parents of the 12-year-old know about what their daughter has been posting," she said.
