Now he's being modest! Justin Bieber covers up in bulky jersey at vitamin shop... after being booed for flaunting his physique at Fashion Rocks

By John Lopez for MailOnline

On Tuesday he stripped down to his underwear following a less than warm welcome at the star-studded Fashion Rocks show.

But now Justin Bieber has covered up his six pack abs as he ventured to a GNC health and nutrition shoppe in New York on Wednesday.

The 20-year-old donned a red Toronto Blue Jays jersey and a black baseball cap as he waited patiently in line to pay for his purchases.

With his tatted-up arms in full display, he teamed the sporty ensemble with a pair of black drop crotch bottoms and black trainers.

As his hat teetered on the edge of his head, Justin snacked on what appeared to be a piece of beef jerky while holding a plastic bag in the queue.

Although the popular chain is stocked with various vitamins, minerals and sports supplements, one of the members of his entourage was spotted holding a bottle of Melatonin, a natural sleep aid.

The Boyfriend singer's retail outing comes after he was booed while taking the stage at the Fashion Rocks concert in New York City on Tuesday night.

Wearing a powder blue blazer, black tank top and dark jeans he paired up with model Lara Stone to introduce singer Rita Ora and unexpectedly received the negative reception from the audience.

Seeming unfazed, he turned to Lara and said, 'I don't feel comfortable unless I'm in my Calvins. So, what's up? Is that cool?'

Without waiting for an answer Justin then disrobed down to his black Calvin Klein underwear and exposed his ripped physique.

The Baby singer then struck some awkward Zoolander style poses before he slightly muffed the next few lines on the teleprompter.
