Taylor Swift 'Hates' Justin Bieber, Selena Gomez Feud Rumors [VIDEO]: Trouble Rises for Besties Over Ex-Boyfriend Drama, Forgives Harry Styles

Is there a feud brewing between best friends Taylor Swift and Selena Gomez? According to some sources there could be thanks to the "22" songstress' alleged disdain for Gomez's ex, pop star Justin Bieber. Though Gomez and Swift have been spending a lot of time together, with Taylor attempting to set up Selena with numerous friends, some are saying that the two might have a falling out soon.

"Taylor hates him," a source revealed to Us Weekly. "She thinks Selena makes a mistake every time she reconciles with him," "Bieber has really come between the girls."

As a result of this hatred for Bieber, a rift has allegedly developed between the two songstresses. Swift was a no-show for Selena's 21^st birthday bash, but Justin ended up showing up. Though she tweeted a special message to Selena on her actual birthday, people are viewing this as Taylor and Gomez feuding. Though other sources claim Swift didn't go to the party because Justin was invited. That sounds like the most likely reason, but who knows?

Also, remember this?

What do you think of these rumors?

Mstars recently reported on Taylor's incessant attempts to hook Selena up with another guy. Here is an excerpt:

"It was (Taylor's) idea to push Austin and Selena together because she really likes Austin and thinks he would be a good distraction for Selena right now. She did the same with Ed (Sheeran) and Selena, but so far Selena is keeping it strictly friends with both of them," an insider explained. Both Mahone and Sheeran have opened for Taylor's "Red" Tour recently, so it looks like a pattern might be forming. Swift's openers get set up with her friends, apparently!

"But Taylor is going to keep trying, she loves hooking up her friends and especially Selena, because she wants to see her with anyone but Justin (Bieber)! Selena has a bad habit of taking Justin back again and again so even though she swears it's over for good I'm sure Taylor's a little worried that she'll cave in again," the source added.
