With Selena Gomez and Justin Bieber reportedly back together, Taylor Swift no longer wants to deal with the infamously on-and-off-again couple's drama.

The troubled Canadian pop star apparently initiated the reunion after stirring racism controversy over two leaked videos, which show him using the N-word. "Justin reached out to Selena when he was getting tons of backlash for his controversial race joke," a source revealed to Hollywood Life. "He told Selena that he really missed her, that she was the only one who truly understood him and that he needed her by his side."

On top of that, Beiber convinced Gomez to fly to Canada for a weekend to celebrate his father Jeremy's birthday together at a private cottage, along with his siblings and friends. A family friend of Jeremy's girlfriend, Victoria Nosko, was also celebrating her birthday and tweeted on June 8: "Had an awesome b day weekend. Thanks to @ErinWagner @JeremyBieber @justinbieber @selenagomez @CrazyKhalil had a blast!!" However, she soon deleted the tweet and posted the same message without Selena Gomez's name.

"He said that his dad's birthday celebration wouldn't be the same without her because she was part of the family," the source added. "He also told her that she was his one and only soul mate and that he was lost without her. Words that Selena had longed to hear, even though she's basically heard them before. Yep, they are crazy about each other... once again."

According to another source, Taylor Swift is not happy about her former friend getting back together with the "Bad Day" singer. "Taylor is completely baffled that Selena has yet again taken Justin back," a source close to Swift claimed. "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."

"Taylor is convinced that this relationship has and will ruin her health and life, but she is finished with trying to help," the source added. "She feels like she has tried enough and it hasn't worked."
