A source told Us magazine that the ‘You Belong With Me’ singer hates Bieber and thinks that Gomez makes a mistake reconciling with him time and again.
The insider has also revealed that Bieber is coming in between the ‘Wizards of Waverly Place’ star and Swift.
The 23-year-old singer also refused to answer questions about the 19-year-old popstar at the Billboard Music Awards in May.
A Bieber insider has also revealed that the ‘hatred’ is mutual as he keeps on complaining how Swift keeps on telling her 21-year-old best friend that she can do better.
Swift had earlier tweeted that Gomez was the closest thing she has ever had to a sister.
