Selena Gomez and Justin Bieber's break up might have been caused by an affair he had with Victoria's Secret model Miranda Kerr, new rumors suggest.

Miranda Kerr, who recently broke up with longtime boyfriend Orlando Bloom, might have had an affair with Justin Bieber while he was dating ex-girlfriend Selena Gomez, according to the International Business Times.

The rumors sparked after photos of the "Heartbreaker" star emerged featuring him cuddling with the Victoria's Secret model at one of the company's fashion shows.

While rumors about the alleged affair have not been validated, they have certainly caught the attention of fans around the world who want to know more about Justin Bieber and Selena Gomez's break up.

Justin Bieber released a new song from his upcoming album entitled "Recovery," with lyrics that discuss his emotions involving his break up with ex-girlfriend Selena Gomez.

"If it's going to sleep alone at night/I don't wanna close my eyes," one of the lyrics reads, leaving fans wondering if he is still getting over Selena Gomez.

Another part of Justin Bieber's new song also says "First, I'll acknowledge, all trust has been broken, a successful recovery I pray for us at night, grants me with a second chance, never thought I'd see your face again," giving ominous mentions to the couple's break-up process.

Last week, Selena Gomez confessed that she has not been on a date since her break-up with Justin Bieber - a revelation that left of her fans questioning if she will get back with him.

"Do you know I've been asked out on one date, that's it?" Selena explained to Zach Sang and the Gang radio host, Zach Sang, Hollywood Life reports.

Selena Gomez also spearheaded an emotional performance in Brooklyn a few weeks ago, where she sang her "Love Will Remember" song and cried on stage. The performance came just after Justin Bieber released his "All That Matters" track where he discussed his "gut-wrenching" relationship.
