I didnt find it disrespectful. I actually found Tyra disrespectful with the way she approached the situation.
I clearly remember Tyra sticking her finger in her mouth, to indicate a gap being there and saying "Eathzy, breethzy, beautifu-ul-- CovurGurl...do you think you can get a CoverGirl contract like that?"
Umm..she did get a contract, didn't she? And I think if Tyra was really worried, she wouldve gotten her lessons to fix her speech problem.
Thats a problem I have with society today; no one seems to think you can be beautiful with the littlest flaw, even when that flaw in actually isn't something that makes you any less beautiful.
For instance, Ive noticed kids my age a lot of times thinking "Oh my, I have a crooked tooth. I need braces." And it really irks me for some reason.
I have a gap. Granted, its not nearly the size of Dani's, but Ive learned to live with it. I dont need to have perfect teeth.
Then again, I guess as a model, it was the right choice.
