Olympic gymnast Nastia Liukin is arching her back in latex pants with no shirt as piles of snow mount up in her Dallas, TX location. The 31-year-old five-time Olympic medalist, who stripped down to a bikini this weekend to help fight the forecasted six inches of snow in the Dallas-Fort Worth Area, was back to adding her signature twist on Instagram last night – instead of appearing all bundled-up and with a fresh blanketing around her, Nastia was out in the sun.
