According to Hollywoodlife.com, Justin was upset that he wasn't invited to Tay's party as Selena Gomez's date. Pretty much every A-list singer was there including Beyonce and Jay Z, so why not the Biebs? Ahem, don't you guys remember that grossed-out-tongue-moment that went down at that awards show when Jelena kissed?
GossipCop.com is reporting that Justin was clearly on the west coast working in the studio during the party time. Their source told them that he wasn't "bummed" about not going, and didn't even expect to get invited to her party.
All of this comes after reports hit yesterday that Selena had a breakdown at Taylor's party because of Justin. You can read about that, here.
