This should surprise no one, but guess what, you guys? Taylor Swift hates Justin Bieber and he's been driving a rift between her and Selena Gomez.

We think she's harboring a grudge against Da Biebs because of that whole 'Punk'd' incident and the fact that he dated her BFF Gomez, preventing them from hanging out more and baking stuff at Lonely Girls Club meetings. That's just our lil' theory…

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

It wouldn't be the first time a guy has driven a wedge between two good girlfriends in history. It happens.

But Swift seems to harbor a raging disdain for The Biebs, which feels sorta new and unbecoming of America's Sweetheart. Like, she doesn't even seem this mad at her nemesis Kanye West.

Recently, she stuck out her tongue at The Biebs and intimated that she is not a fan in an interview.

Did they have a secret affair or something? Did that cause the bitterness? Oh wait, we didn't mean to open that can of worms…

...but wouldn't it be hilarious if Yeezy and The Biebs teamed up for a T. Swizzle diss track?They would be Yeez it to Biebs!
