Selena Gomez's past relationship with Justin Bieber was plagued by rumors of cheating but according to a new report, their recently reconciled relationship is starting off in a much better place.

One year after Gomez infamously called out Bieber on Instagram for cheating on her multiple times during their years-long relationship, a source claims Bieber is doing whatever it takes to prove himself to his on-again, off-again girlfriend.

“Selena is blown away by Justin’s new integrity,” a source close to the couple told Hollywood Life on Nov. 10. “Since they’ve reunited, Justin now keeps every promise he makes, and is doing everything he says he is going to do. Selena feels secure in their relationship because he is making it easy for her to trust him completely.”

Gomez and Bieber started dating in 2010 and continued to date exclusively until 2012. Since then, the couple has been spotted together from time to time but never actually confirmed whether or not they were back together. At the same time, Bieber was seen with a number of other women, including Kourtney Kardashian, Hailey Baldwin, and Sofia Richie, but never confirmed if he dated any one of them.

“Justin has grown, matured and has really changed a lot in the last few years,” the source revealed. “She is falling in love all over again with a new and improved Justin who calls when he says he is going to call, texts when he says he will and is doing everything right.”

Gomez appeared to stay single in the years after her late 2012 split from Bieber but then, in January of this year, after being briefly linked to Orlando Bloom and even Brad Pitt, she went public with The Weeknd after enjoying a romantic meal in Los Angeles. Throughout her relationship with The Weeknd, Gomez was seen with her fellow musician on numerous occasions around the world and even enjoyed a days-long trip to Italy to sight see in Venice and Florence in February.
While Gomez and The Weeknd appeared to be going strong just weeks ago, the couple's split was confirmed earlier this month — days after Gomez and Bieber attempted to reunite in secret at her L.A. home. Since then, Gomez and Bieber have been spending tons of time together and appear to be involved in a committed relationship once again.
