Lexy Panterra -- Twerkin' Out The First Pitch ... At Miami Marlins Game

Here's celebrity twerk instructor Lexy Panterra throwing out the first pitch at a Miami Marlins game moments ago ... and twerking while she does it of course.

Lexy's a big deal who's taught the art of the twerk to celebrities like Mel B, Christina Millian, and Tiny so it makes sense the Marlins would have her toss one out.

Look ... we're not gonna get too deep here ... her pitch was fine (better than 50 Cent) but this is all about the little wiggle she gives before the throw, and the big wiggle in her video below.

Enjoy.
