Selena Gomez is in her element, looking very polished and beautiful while away from ex-boyfriend Justin Bieber. The on-again-off-again relationship of the two young celebrities seems to have hit rock bottom last January 2014 and they have not been spotted together since.

Justin Bieber is in all kinds of trouble with multiple cases ranging from assault to vandalism in the last month alone, but Selena Gomez, on the other hand, has been stepping out in crop tops and shorts.

Here she is at Heathrow airport flashing that taut tummy before leaving the U.K. and before that, she was spotted walking around California wearing this belly-bearing number.

Following the cancelation of the Australian leg of her latest tour, it was revealed that the singer had voluntarily checked in to rehab for two weeks in January. People wrote that Gomez quietly went to Dawn at the Meadows last January 5, but it is not due to substance abuse.

"It has become clear to me and those close to me that after many years putting my work first, I need to spend some time on myself in order to be the best person I can be," said Selena in a statement.

During this time, sources said that the "Getaway" star needed a break from her busy acting and touring schedule, while other insiders said Gomez was emotionally drained and struggling with her tumultuous relationship with the 19-year-old bad boy, Beiber.

Mirror wrote that close friends were worried that her partying was getting out of control and "Her friends and family became increasingly worried that there might be a serious problem with Selena." She was encouraged to go to rehab and seek professional help.

It's looking as if the intervention, whether due to fatigue or emotional distress, helped the young star. She's been looking better than ever and people cannot help but note that it's all happening because she's been staying away from Bieber.
