Selena Gomez NOT Dating Niall Horan, Back With Ex-Boyfriend Justin Bieber? Taylor Swift Allegedly ‘Done Trying To Help’ Songstress Best Friend

Justin Bieber and Selena Gomez might be dating again and Taylor Swift is allegedly pretty mad at her Stars Dance best friend. After a suspicious photo of Selena and Justin getting pretty intimate popped up on Gomez's Instagram account and then was promptly deleted, we can pretty much assume the two are rekindling their romance, but not everyone is on board with this.

"Taylor is completely baffled that Selena has yet again taken Justin back. She thinks that Selena is a lost soul and nothing will make her realize how bad Justin is until she no longer has a career," a source told HollywoodLife.com. "Taylor is convinced that this relationship has and will ruin her health and life but she is finished with trying to help, she feels like she has tried enough and it hasn't worked."

We all know that Taylor is definitely not a Belieber, especially when it comes to him dating Selena, so this insider's claims could definitely be true. Though the "source" is talking to the same website claiming Selena "hates" Justin and is using her anger to write new song ... so we're not exactly ready to confirm this new rumor!

Plus, isn't Selena supposed to be dating One Direction's Irish heartthrob Niall Horan? The two were spotted at a Katy Perry concert last month and rumors have been flying around the Internet ever since. Unfortunately new speculation pushes old gossip out of the way, so maybe Niall is out of the picture in Selena's love life.
