ANSWER:GAP!

Lara, Vanessa and Lauren have in common (among other things)...
Their lovely fron teeth gap!




I'm aware that many people really can't stand it and find that gap ugly, but I love gap toothed people. Of course, when they are fabulous models it looks even better, haha.
I think it's very cute and beautiful!
And it can be iconic, like with these three ladies above.
