Selena Gomez shared several images of herself as a blonde on Instagram prior to Sunday night's American Music Awards and right away, Justin Bieber "liked" the image.

Because Gomez and Bieber have been spending so much time together in recent weeks, the Instagram "like" wasn't a surprise. However, after the 23-year-old "Friends" singer chose to "unlike" the image days later, he quickly sparked rumors of possible tension, or even a split, between them.

On Nov. 21, Hollywood Life shared details of Bieber's "unlike" of Gomez's photo, revealing that the singer was caught by several fans online who questioned why he would do such a thing.

Selena feels secure in their relationship because he is making it easy for her to trust him completely.”

“Justin has grown, matured and has really changed a lot in the last few years,” the source added. “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.”
