His actions have made it very clear that he no longer wishes to be seen as a child star.

And Justin Bieber took to his Instagram on Sunday to remind the world that he is not the only one who is getting older.

The 19-year-old pop star shared a lone bra lying face down on the stage from his show – an expression of support from an overly excited fan.

He simply captioned the picture: ‘I guess everyone grows up.’

Because he started his career at such a tender age, Justin’s fans are growing up alongside him.

Where shrilling pre-teens would have previously thrown stuffed animals and held glittery signs in the air, young women are now tossing their undergarments onstage.

The Beauty And The Beat singer recently opened up about what it’s like to grow up under the attentive eye of the modern-day media.

When accepting the Milestone Award during the Billboard Music Awards in May, he stood up for himself while a handful of crowd members booed.

‘This is not a gimmick, and I’m an artist, and I should be taken seriously.’
