Huh? Justin Bieber Wears Gas Mask On London Shopping Trip

Has Justin Bieber gone all Star Wars on us?

The 18-year-old pop star inexplicably wore a black gas mask with the rest of his all-black outfit while shopping in London, England on Monday, and we've got all the photos for you right here on RadarOnline.com.

Some reports speculated he wore it as a disguise, as he's been known to attract mobs when out in public. In 2012, he tweeted, "i am the #masterofdisguise," when he went shopping in Venice Beach, Calif., wearing a mask.

British publication The Mirror reported that like Taylor Swift, the Canadian pop icon has ventured over the pond for his latest courtship, as he's been seen with singer Ella-Paige Clarke.
