Bieber causing rift between Swift, Gomez?

Singer Taylor Swift reportedly does not approve of friend Selena Gomez's on-and-off relationship with singer Justin Bieber. This has caused trouble in the ladies' friendship.

Swift, 23, feels that Gomez is committing a mistake by giving Bieber repeated second chances, reports Us Weekly magazine.

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

Meanwhile Bieber is also not pleased with Swift's constant interference.

"He complains Taylor's always telling Selena she can do better," a source said.
