Recently, it was reported that the on-and-off couple spent the night together, after the 20-year-old singer was spotted being dropped at her home, in Bieber's car, which was driven by his bodyguard.

"Selena looks like a young girl in love. And obviously Justin's trying to win her back - sending her home in his car and everything - giving her the royal treatment," one of the photographers said.

The 19-year-old had recently sparked a series of controversies- hooking up with a nursing student, groping a fan in Miami, he was photographed smoking what may have been marijuana. The youngster also posted a picture of his buttocks on Instagram and Twitter.

During an interview with Billboard magazine, the Beauty and A Beat singer confessed he was struggling to get over his break-up from Gomez.

"I'm not in the happiest place that I've ever been. I'm trying to get through what I'm going through. Like I said, I have my really close friends to cheer me up and keep me going," he said, adding, "There are so many rumors. People say I call Selena every day and she won't pick up the phone or I'm chasing her down, and these are all fake stories."
