Selena Gomez‘s on-and-off relationship with Justin Bieber is reportedly causing a rift between her and her BFF Taylor Swift.

According to Us Weekly, the 23-year-old country crooner isn’t a fan of how Justin treated Sel in the past.

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

Apparently, the feeling is mutual. Another source added, “[Justin] complains Taylor‘s always telling Selena she can do better.” Yikes!
