Lexy Panterra is some fitness chick who made a name for herself in 2015 teaching "TwerkOut" -- some weird form of exercise where you're twerking.
In January 2016, she danced on the wall surrounding the Bellagio fountain, which has gotten tens of millions of internet plays:
Oddly most people were ignoring her dance, which I assume is because it was mostly couples around her, and I think the dudes were afraid to look and then get shit from their wives/girlfriends.
Now age 29, she's apparently dating a 19-year-old: http://www.dailymail.co.uk/tvshowbiz...fast-food.html
