Justin Bieber and Selena Gomez broke up and patched things up just like that - in a flick of the finger. This makes people around them worried that the two are moving too fast. A new report shares that indeed, the two are moving too fast, with Justin Bieber already out shopping for an engagement ring for Selena Gomez! This, in spite of the fact that Justin Bieber had been caught staring at Wiz Khalifa's Amber Rose's cleavage on a photo, questioning his sincerity to be Gomez's one and only and his maturity level, again, Mail Online UK reports.

According to Mail Online UK, Justin Bieber was so excited and happy to hang out with Wiz Khalifa's wife Amber Rose on Thursday that he cannot help himself but request for a picture. However, instead of smiling for the camera, the picture showed him looking at busty Amber Rose's cleavage. Justin himself posted the telling picture on his Instagram. Amber was probably unaware of where Justin's eyes were trained because she was looking into the camera and smiling. After Justin posted the picture on Instagram, Amber Rose posted the picture on her own Instagram and captioned it with, 'The Biebs @justinbieber wanted a pic with Muva and I him. He's a sweetie pie.'

This does not suggest they are together or anything, but Mail Online UK puts forward that this photo questions Justin's ability to be loyal to Selena Gomez. According to Mail Online, "His on/off relationship with Selena Gomez is back on at the moment but that doesn't mean Justin Bieber can't look at other women."

Selena Gomez however, have already claimed when she and Bieber reconciled that she has 100% trust on Justin Bieber so the picture might not cause any harm. As previously reported, Selena Gomez already said she did not return to Justin Bieber without any plans of becoming the next Mrs. Bieber, so she really must trust him now. In fact, the two are so sure of their feelings for each other that getting engaged might be their next move already.

"Justin is talking about proposing to Selena, he's looking for the perfect rock for his princess," an insider shared to HollywoodLife.com. "He's been telling her she's the only girl for him, that he's ready to settle down and have babies."
