We may now know the reason why Taylor Swift disapproves of Selena Gomez's on-again, off-again relationship with Justin Bieber. 

In a new interview with Glamour UK, the pop star seems to hint that Bieber cheated on Gomez, one of her best friends.

Speaking about her own love life, the "22" singer said told Glamour UK, "I've seen my friends take someone back after they've cheated because they fit perfectly."

Although she doesn't specifically reference the couple, there's speculation that she may be talking about Gomez and Beiber's relationship, which she has disdained. 

Back in May, Swift was caught sticking her tongue out in disgust as she walked by Gomez and Bieber kissing backstage at the Billboard Music Awards.

Taylor also scowled during the interview when asked about an article in August that rumored she didn't think the 19-year-old Canadian singer was good enough for Gomez. "Oh, Selena and I laughed hysterically on the phone about that," she said.

On one hand, it's possible that Taylor and Selena were laughing because the report was wrong, but the rest of the interview makes it seem like they were amused because the story was so right.

When the interviewer asked Taylor if the previous report was true, she coyly responded, "Does it matter?"

It's possible to think that she answered a question with another question to avoid the subject altogether because her dislike of Bieber has become all too obvious.

Rumors of Bieber stepping out on Selena date back to the end of last year.

A few weeks prior to the couple's split in December, Bieber was spotted backstage at the Victoria's Secret Fashion Show, allegedly getting very cozy with model Barbara Palvin. However, he and Selena posed together in multiple Instagram shots since then and Selena has refrained from saying anything negative about her ex in public.
