Pop star Justin Bieber tweeted an Instagram photo of his bare bums to his 33 million Twitter fans on Jan. 19, but deleted then promptly deleted the snapshot shortly afterward.
Justin, 18, appears thin but toned in the photo, in which he wears a baseball cap and a black tank top. The lanky 5-foot-7 Bieber has been tweeting more and more photos of his bare body recently to show off the results of his new workout routine.
“I’ve been working out in the gym, getting bigger, trying to get sexy for the ladies," he said in November 2012, around the time he tweeted a photo of himself shirtless baring his six-pack abs.
A month later, Justin flaunted his rippling biceps at a concert stop in Philadelphia. While Bieber is very thin, he's a talented all-around athlete who excels at basketball, skateboarding and ice hockey.
Despite his hectic schedule, Bieber, who suffers from insomnia, takes off one day a week to relax, hang out with friends and catch up on sleep.
"We try to take off at least one day a week for me to be a regular kid, go play basketball, hang out with my friends and, you know, just do what I like to do," he said. "Sometimes for that day I just sleep all day because the six days before I'm exhausted."
While his work and travel schedule are relentless and chaotic, Justin tries to be as normal as possible and appreciates his success.
"I try to be as normal as I can with the abnormal life that I have," he said. "It's definitely not normal, and there’s so many sacrifices that I’ve had to do, but at the end of the day, I’ve been able to do so much that I would have never been able to do."
