haha I don't think miss south carolina has taken the mcat or would score too highly if she did...
Honestly I would suggest you put it in. It really is a unique EC not too many girls can brag about. Make sure you don't make it look superficial. If ever asked, focus on how it matured you as a person, yada yada, etc. Keep in mind a couple of people here and there may be superficial and make associations about your ability to be in medicine on something as simple as that. But it really shouldn't be a problem if you have great grades and mcat, and a few other EC thrown in there, like volunteering, shadowing, etc.
Maybe include some of your competition pictures in the file? 😀 (kidding...unless...nm)
