Just when everything seemed to be okay between two of Tinseltown's controversial young stars, Justin Bieber and Selena Gomez break up again took place. This time, the falling apart is allegedly caused by Kylie Jenner.

As per one of Radar Online's sources, Justin Bieber and Selena Gomez break up happened because the 'Come and Get It' songstress found out that Jenner had been sending flirty text messages to the Canadian crooner.

Apart from the text messages, the 'Keeping Up with the Kardashians' star allegedly sent photos of herself which Gomez eventually saw.

"Selena flipped out and there was a huge fight between the girls. She now wants nothing to do with Kylie or [her sister] Kendall," claimed the source. Although the former Disney actress was spotted having fun with the Jenner sisters during the Coachella Valley Music and Arts Festival, she deleted all of her Instagram snapshots with them which made fans speculate about a brewing feud.

Gomez was likewise seen cuddling with Bieber during the famed festival earlier this month but the brunette beauty allegedly had a "meltdown" days after.

Justin Bieber and Selena Gomez break up might be the reason why the 'Montecarlo' actress is doing her best to regain a cheerful perspective in life. Recently, she gave her social networking accounts a detox by removing several celebrities which she formerly followed like Taylor Swift, Vanessa Hudgens, and Ashley Benson.

The source adds that Gomez is likewise developing a habit to come to church regularly, something which she learned from her brief rehab stint: "Selena is trying to change her ways by going to church and more so to avoid going to rehab. She feels like she has a spiritual gap and that maybe that's why she is struggling."

Meanwhile, the Jenner sisters remain mum about their connection to Justin Bieber and Selena Gomez' break up although Khloe Kardashian expressed her anger towards people who kept on fabricating tales about her "baby sisters".
