Justin Bieber and Selena Gomez are over for good this time - report

Justin Bieber and Selena Gomez are never, ever getting back together -- at least, according to sources close to the former couple.

Us Weekly has learned that Jelena's recent breakup is also their last, as Gomez is now "done with him." The source also calls Bieber a "bad influence," which could be a reference to the recent photo of him smoking pot.

"They had another huge fight, and Selena won't forgive him," an insider says. A different source adds, "He's been really down about the breakup."

Not too down about it, it seems. Bieber rang in the New Year with his friend Lil Twist, and he allegedly "flirted with various girls" while at Los Angeles club Couture. Somehow we doubt that the most eligible bachelor in young Hollywood will have problems picking up another lady.

For her part, Gomez tweeted on New Year's, "New beginnings. Fresh start. I love you all :)"
