London, Mar 30 (IANS): Pop star Justin Bieber has reportedly become an egomaniac as now he doesn't have ex-girlfriend Selena Gomez to keep him grounded. He reportedly makes his entourage watch his videos over and over again.

The 19-year-old broke up with actress Gomez earlier this year, and without her guidance he hasn't been able to keep himself grounded, according to a report in femalefirst.co.uk.

A source revealed how Bieber has been reliving his 2011 appearance as the host on "Saturday Night Live" by replaying the tape along with his own videos to his entourage on the tour bus.

"It's so awkward. I mean Bieber did a good job on the show, but no one wants to watch it again and again," femalefirst.co.uk quoted a source as saying.

"He makes us watch the videos again and again, but no one says anything. Gomez used to tell him what was up and it must have helped keep him grounded, because since they broke up his ego is out of control," the source added.

The source said that the 19-year-old doesn't act quite as cocky when he's around people he respects, but his entourage don't want to speak out.

"He never pulls that kind of stuff when Jayden Smith or someone else he respects is there, but when it's just his people on the bus he does it," the source said.

"He does the same thing with his videos. He'll have them running on a loop, and then when he sees a part he loves, he stops and rewinds it and makes everyone watch," the source added.
