Is Justin Bieber Mad That He Wasn't at Taylor Swift's Birthday With Selena Gomez?

Justin Bieber is reportedly upset that he wasn't invited to Taylor Swift's 25th birthday with Selena Gomez! According to rumors, the singer thinks he should have been there — and is annoyed that "The Heart Wants What It Wants" singer's friends aren't his biggest fans.

“He was bummed when he heard who went. He feels like he really should have been there," the source said.

"He doesn’t have a problem with Taylor, but he knows she just doesn’t get him. And for that reason he thinks Taylor doesn’t get Justin and Selena as a couple. It’s frustrating for him and frustrating that Taylor didn’t include him considering how close she is to Selena.”

Since we've heard that the "Blank Space" singer isn't a Jelena fan, we would understand why she wouldn't invite him. He's not her bestie!

Besides, he's been hanging out with Kendall Jenner and Hailey Baldwin lately, so at least he's been getting the support of his own friends.

Plus, it's probably for the best that he wasn't there. Although there was allegedly drama at the event, it seems like the 1989's birthday was a calm affair. Considering how emotional Selena gets over her ex, they may be better off hanging out in private.
