Taylor Swift and her Instragram are very famous. We can't deny this.

The country singer is well known for constantly posting Instagram pictures of herself with her famous friends. However, due to recent events, it seems that the Taylor Swift clan may be shifting.

Taylor Swift's BFF Selena Gomez recently unfollowed the "Dear John" singer on Instagram, along with a list of celebrities, including the Jenners.

Selena Gomez has moved on to her new celebrity BFF, Katy Perry, according to HollywoodLife.

The 21-year-old singer has also decided to hire Katy's manager Bradford Cobb after firing her parents.

Perry is reportedly also helping with the other big change in Selena's life, the breakup with Justin Bieber.

A source told the gossip website, "Katy has been helping Selena, she's doing everything she can to help her right now as far as being a shoulder to cry on, someone to talk to that will understand."

The insider continued, "She's like a big sister to her, a nonjudgemental big sister. Katy doesn't push her opinions on Selena, but whenever Selena needs her, she is there for her."

Katy is also reportedly teaching Selena about the "womanizers" in Hollywood.

"Compared to Russell Brand or John Mayer, Justin is still a kid. Those guys are real womanizers so Katy knows exactly what Selena is dealing with," the source added.

Although the break in the friendship might be a song worth writing about for Taylor Swift, she may have moved on.

Hailee Steinfeld, who frequently appears on Taylor Swift's Instagram as well, told Nylon Magazine that the 24-year-old is "an amazing friend," according to E! News.

The actress stated, "I always get the 'Tell us something nobody knows about Taylor question. And it's like, we both respect each other tremendously, but we choose to keep our friendship out of the public eye."

The "3 Days to Kill" added, "She's a really great person and an inspiration to me and many others."
