Jessie J Shows Off Killer Legs in New Tights Campaign

Jessie J's biggest stateside exposure to date was arguably as the house artist for the 2011 MTV VMAs, where she memorably performed all night with a broken foot — but in the new ads for English hosiery brand Pretty Polly, Jessie J is standing so tall, we almost didn't recognize her!

In the ad, Jessie rocks her signature cropped black bob and a pair of House of Holland for Pretty Polly suspender-style tights. House of Holland, the cheeky label from U.K. designer Henry Holland, hit the mainstream back in 2006 with fashion-referencing graphic tees bearing text like "Do Me Daily, Christopher Bailey" and "Cause Me Pain, Hedi Slimane." Holland's new line of "statement tights" are similarly bold, as the superhero-themed campaign would suggest, and Jessie looks mighty foxy in hers.

If nothing else, Jessie's work ethic does appear to be indeed superhuman. Her seventh single in less than a year, 'Who You Are,' is set to be officially released in her native U.K. next month, though she has yet to match the success of her global hit 'Price Tag,' which peaked at No. 23 in the U.S.

The single 'Domino' -- Jessie's stateside follow-up to 'Price Tag' -- has stalled on the charts following a promising debut. Meanwhile, Jessie recently swept the MOBO Awards, winning in four out of the five categories in which she was nominated, and is set to serve as a judge and mentor on the upcoming U.K. reboot of 'The Voice.' Keep on your grind, girl!
