Pop sensation Justin Bieber rewarded fans for their patience as they braved a fierce snowstorm while camping outside a Tv studio by treating them to hot pizza.

Despite blizzards battering the America's East Coast, undeterred youngsters began lining up outside NBC Studios in New York City on Friday (08Feb13) to secure their spots in the audience for Bieber's appearance on Saturday Night Live the following night (09Feb13).

The Baby hitmaker was flattered by their devotion, and showed his appreciation by ordering them meals from Ray's Pizza.

Bieber announced the delivery via his Twitter.com page, writing, "Everyone outside be safe. Enjoy the pizza... Bieber on Snl."

The 18-year-old singer didn't seem too fazed by the snow, adding, "(I'm) up real early today for a long day of rehearsals. And now a blizzard is coming. No issue. I'm Canadian."
