Singer Selena Gomez has stopped discussing her beau Justin Bieber with her friend and singer Taylor Swift.

It is believed that Swift is not a huge fan of Bieber. According to sources, being a protective friend, Swift hates the way the "Baby" hitmaker treats Gomez.

Now that the on-off couple have reunited, Swift is supportive of her friend's choices, but she is not getting involved.

"Selena and Taylor don't talk about Justin. Taylor wants nothing to do with him or hear about him, so when they talk they avoid the topic," hollywoodlife.com quoted a source as saying.
