Justin Bieber Posts Bra Pic To Twitter: Times Change - Even Beliebers Grow Up [PHOTO]

Justin Bieber has matured...and his fans have too. Beiber posted a Twitter photo of a bra on the stage with thousands of screaming girls in the background. His caption read, "I guess everyone grows up."

Years ago, tween and pre-teen fans would throw teddy bears onto the stage...but a bra on the stage is decidedly more Rolling Stones and less Raffi.

The photo of the beige bra is a symbol of all that's changed for Bieber through the years. He still has Beliebers...but they're older now.

The photo has received over half a million Likes. It was taken on a stop of Bieber's ongoing Believe world tour.

Beiber, 19, has had a trying few months, but the bra photo is a symbol that he's still loved-albeit in a decidedly sexier way.

Justin got in trouble for driving...well...like a total jerk around Calabasas, California last week and terrorizing his neighbors.

He also had to defend himself after the crowd booed at the Billboard Music Awards.

"I'm 19 years old. I think I'm doing a pretty good job," he said. "Basically from my heart I really just want to say it really should be about the music. It should be about the craft that I'm making. This is not a gimmick, and I'm an artist, and I should be taken seriously."
