Who is Jerry? Justin Bieber's fans are a bit inappropriate, it seems.
If you ever wondered what Justin's nickname "Jerry" was all about, well, it looks like his followers have created the pet name for his... er... penis.
It's even become such a popular subject that it's been trending on Twitter this week.
We guess it had to happen, sooner or later.
In a new interview with London DJ James Barr on Capital FM, he was asked, "Who is Jerry?"
Once armed with the info about Justin's nickname, the DJ asked if it was embarrassing to Biebs.
Justin said, "My fans are a little inappropriate. It's funny. My fans are kind of inappropriate."
Who knows where Jerry even came from? Justin said, "I don't know, it's just what they named it," adding, "Jerry seems kind of like... 'Here's Jerry...'"
Justin isn't above a little fan embarrassment, it seems, tweeting: "alot of jerry talk today. haha. my fans are wild."
At least he has a sense of humor about it!
