Justin Bieber has taken sides in the year’s most heated celebrity battle.

Two weeks after posting a cryptic video about “less hate, more love,” Justin has explicitly referenced the ongoing feud between Taylor Swift and Kanye West, as fueled by Kim Kardashian and her expert Snapchat skills.

Bieber posted a screenshot of himself FaceTiming with Kanye, and just to drive the message home, he captioned it, “Taylor swift what up.”

In case you missed out: Taylor got mad about Kanye’s song “Famous,” which includes the lyrics, “I feel like me and Taylor might still have sex / Why? I made that bitch famous.” Via a PR rep, she condemned the song’s “strong misogynistic message.” Kanye retorted by saying he got permission from Taylor for the lyrics ahead of time.

Later, Kim alleged that Kanye had recorded the phone call where he got permission from Taylor to use the lyrics. Then Kim leaked that recording on Snapchat, proving that Taylor had at least approved the first half of the offending couplet.

Taylor then posted a note to Twitter saying that her real problem was with the word “bitch” and that she didn’t know she was being recorded. She’s been quiet on social media ever since, but that hasn’t stopped her enemies from partying about the whole thing.

Now it seems like she can rank Justin among those enemies. She’s going up against an increasingly stacked team.
