Selena Gomez has reportedly reunited with Justin Bieber but while that ruined her friendship with Taylor Swift once before, this time it's going to be different.

A source told Hollywood Life that Calvin Harris' girlfriend won't ditch Selena Gomez over Justin Bieber.

The source claimed, "Taylor is not over her friendship with Selena, but she is over trying to convince Selena that Justin is awful."

In March last year, Taylor Swift reportedly ditched Selena Gomez after she reunited with Justin Bieber.

"Swift is disgusted that the pair are back together, cutting off her bestie after tweeting just last July that Gomez was 'the closest thing I've ever had to a sister,'" Us Weekly said. "But Gomez rekindling of the Jelena flame isn't the only thing peeving Swift. She believes Gomez 'used' a brief romance with the Grammy winner's pal Ed Sheeran last June to make her jailbird sweetie jealous."

But Taylor Swift and Selena Gomez allegedly quickly ended their feud after the latter split with Justin Bieber for the umpteenth time.

Hollywood Life alleged that Taylor Swift's friendship with Selena Gomez might survive this time but Calvin Harris' girlfriend is disappointed with the whole reunion with Justin Bieber.

According to the report, Taylor Swift was "worried about her tour stop tonight but has heard that [Justin and Selena] got together and she gave the reaction that was basically full of disappointment. People around her are saying Taylor is showing a 'what the f-k!?' type attitude."

And it doesn't mean that the former Disney star will be invited to the "Bad Blood" singer's famous parties, either, because she couldn't take all of Selena Gomez's drama.

"It's definitely one of the reasons," the source said. "Nobody wants the friend who goes against everything you say to get the invites for fun when it's going to be drama and babysitting the whole time."
