Olympic gymnast Nastia Liukin has officially caused a "situation" with no bra and in a totally frontless top. The 31-year-old Russian-born star dropped another of her jaw-dropping fashionista snaps on Instagram yesterday, with the five-time Olympic medalist highlighting everything from her massive thigh gap to her flawless sense of style. Nastia, followed by 1 million, shared sun-drenched snaps taken in her Dallas, TX base, but comments aren't on the street setting. The skimpy looks is topping replies. See why below.
