Taylor Swift is apparently "not a Belieber."
The singer is best friends with Selena Gomez, who has an on/off relationship with teen heartthrob Justin Bieber.
According to insiders, Taylor doesn't approve of Selena rekindling things with Justin, but is keeping quiet to maintain the friendship between them.
"Let's just put it this way: Taylor is not a Belieber," a source close to the girls told RadarOnline.
"She loves Selena and wants her to be happy but she doesn't think going back and forth with Justin is the answer. That being said, Taylor's also a little bit jealous in a weird way."
Earlier this month Selena confirmed to a Boston radio station that she was single again. However, at the Billboard Music Awards last weekend the 20-year-old was spotted giving Justin a kiss backstage, with Taylor seen pulling a face in disgust.
The insider says Taylor's jealousy stems from the fact her best friend's attention has been taken so easily by the 19-year-old popstar once again.
Known for being a serial dater herself, Taylor is said to be doubly annoyed by the fact she is currently single.
"Taylor is jealous that Selena still has Justin as 'her person' to go to, but she's not jealous of who Selena's on and off with," the source said.
"She thinks Justin is a brat and that Selena could do way better."
Meanwhile Selena has insisted that she is still on good terms with Taylor. This is despite the behind-the-scenes footage that emerged showing the face pulling incident at the awards ceremony.
"Taylor is my good friend, I presented her award. I love her; she's so cool, normal and down to earth. She's the girl you call when you are going through any heartache. Just listen to her songs and you'll feel better," Selena gushed to BBC Radio 1 earlier this week. "I love Taylor, she's the best."
