Well it finally happened. The moment millions of teenage girls have waited for. Justin Beiber is single once again! Bieber and Selena Gomez apparently called it quits sometime around Halloween and one source says, quote, "Because of their crazy schedules, it was getting harder and harder to maintain a relationship."

But who did the dumping? Did Selena get tired of beating off waves of teenage groupies left and right or did the Biebs find someone new? Some say it was because of Justin's new friendship with Victory Secret's model Barbara Palvin. He performed for the fashion show on November 7 and according to one source he was playing the field during the show, asking for phone numbers and hitting on the models all day. After the show Palvin tweeted, quote, "okay sooo because u guys were askin for it! with ‪@justinbieber ! you were great tonight!" She then added a photo of herself posing with Justin, which you can see to your right.

The next night Beiber, Palvin and a group of people went to see "The Lion King" on Broadway and afterwards Barbara Tweeted, quote, "hey everyone. please calm down. he is all yours!! :) please :)."

A little later she tweeted quote, "There is nothing going on with him. I met him and did a pic with him. Wouldn't you do the same? #friendship"

In an interview on Saturday with Justin he seemed confused about what was going on and when asked about the breakup said quote, "I don't know what to say. I don't know what's going on in my life. To even assess that, it doesn't make sense 'cause I have not made any comment."

A source has reported to TMZ that Justin didn't want the breakup to go down and that he is confident him and Selena will patch things up.

And Yesterday Justin performed an acoustic version of Justin Timberlake's "Cry Me a River" in Boston, which you can watch below. After the show he Tweeted, quote, "Thank you Boston. Focused on the positive. #30MillionBeliebers with me. I'm never leaving you because you are always there for me."
