Justin Bieber Gives Singapore Topless Almost Bottomless Eyeful [Video]

Justin Bieber thrilled fans at his closing show for the Formula 1 Singapore Grand Prix on Monday night, by not only going shirtless but almost displaying a full moon when his pants slipped perilously low.

Kicking off the Asia leg of his Believe tour in showman-like style, the 19-year-old reportedly drove fans wild with flirtatious dance moves and pelvic thrusting throughout his 90 minute hit-packed set.

But Bieber saved his most daring set-piece for the end of his dynamic concert. Pulling off his shirt during the closers “Boyfriend” and “Baby,” about 12-000 females reportedly screamed at the sight of the teen star’s ripped torso.

There was more to come.

As Justin jumped around the Singapore stage, his black leather drop-crotch pants edged down his hips, giving the audience an eyeful of his white boxers.

Seemingly unfazed by his brush with full moon immodesty, the Biebs merely held his mic with one hand and hung on to his pants with the other.

Oddly, there were no complaints from fans in the audience over the Canadian’s shirtlessness, or his posterior display.

Back stateside, Miley Cyrus has been holding forth on Justin’s ability to disrobe at will.

“I’m not much older than him, so I never want it to feel like I’m mentoring him. But I do mentor him in a way,” Cyrus told the magazine.

The new queen of Twerk went on: ‘Because I’ve been doing this s*** for a long time, and I already transitioned, and I don’t think he’s quite done it yet.

Praising Bieber’s abilities, Miley adds: ‘He’s trying really hard. People don’t take him seriously, but he really can plathe drums, he really can play guitar, he really can sing. I just don’t want to see him f*** that up, to where people think he’s Vanilla Ice. I tell him that. Like, “You don’t want to become a joke. When you go out, don’t start s***. Don’t come in shirtless.”‘

After Singapore, the teen star is set to perform in Bangkok, Thailand on September 26. A string of Asia dates including Beijing, Shanghai, and Korea follow, where its rumored native superstars Psy and Big Bang’s G-Dragon may join him onstage.

In October, amid a fresh, solo music release from the singer, the tour jumps to Latin America, New Zealand and Australia with the 15-month trek wrapping on December 8 in Perth.

And if all that isn’t enough, Bieber’s movie-docu Believe is expected to hit theaters between Christmas and the New Year.
