#1 Definitely Don't: Carmella and Paul Van Dale

Whether you love or hate the current SmackDown Live Women's Champion, it's impossible to deny the fact that "The Princess Of Staten Island" is a great (and attractive) heel.
Speaking in terms of looks, Carmella has certainly acquired them from her mother, as there is not much of a resemblance between Carmella and her father (and former WWE performer) Paul Van Dale.
That said, some fans may pick Carmella apart for not being on the same level in-ring wise as Charlotte Flair, Becky Lynch among others, but she definitely has charisma and that heelish personality. While there is a good chance that Carmella will end up losing the Women's Championship at SummerSlam this weekend, she has proved that she's a valuable asset to the company regardless.
