Selena Gomez is worried about former boyfriend Justin Bieber after he took to Instagram on 23 May and called the 2016 Billboard Music Awards "hollow". The All That Matters singer was honoured with the top male artist award at the event.

A source told HollywoodLife that Same Of Love singer is concerned Bieber is "pushing himself too hard".

"Selena isn't quite sure what happened to Justin during the Billboard Music Awards, but she is concerned. She's worried that maybe he's pushing himself too hard and is glad that he has a bit of a break now," a source told the website.

"He seemed fine the last time they communicated, but Selena knows he can be hard on himself. She's not angry at him, she feels for him and hopes he's surrounded by supportive friends right now," the source added.

The 22-year-old singer posted a lengthy message sharing his thought on the lack of authenticity at the award ceremony.

In a lengthy post, Bieber wrote: "I don't know about these award shows.. No disrespect to anybody at any of the shows or the people running it. Nothing but love for you guys and your support. But I don't feel good when I'm there nor after. I try to think of it as a celebration but can't help feeling like people are rating and grading my performance."

"A lot of people in the audience there to be seem worried about how much camera time they will get or who they can network with. When I'm doing a regular show I feel they are there for the right reasons and to strictly have a good time! But these award shows seem so hollow."

"I get the premise is to award people for their accomplishments, but is it really? Because when I look in the audience I see a bunch of fake smiles so that when the camera hits them they look happy. Sure there are people truly proud of others so I don't want to knock them I'm just looking at the vast majority," Bieber said.

"I just think to myself if I'm living my purpose I want the reward to be fulfillment. I'm getting awarded for the things that I'm doing and not for who I am which is understandable I know it would probably be hard to calculate and award someone's spirit lol. But When I do get these awards the temptation of putting my worth in what I do is so hard to fight!!!"

"I am privileged and honored to be recognized by my peers in but in these settings I can't feel the recognition," Bieber added.

"There's an authenticity missing that I crave! And I wonder does anybody else.. Sorry not sorry about grammar it's not my strong point."
