I think the bad makeup is part of her character really.
She can't be her goofy self if she doesn't look like a clown.
More like the E can't rationalize a woman being multifaceted. Hot and funny just seems to short their brains out. Same way they failed with another Aussie, ironically; Emma. They made her first character solely about being quirky, and her second one was supposed to be just about being attractive.
To be fair though, the E has issues with letting anyone have layers.
See also: people screaming at E to be serious all the time, their continued failure to capitalize anymore on characters with natural tweener energy, etc.
Hate to see it with BK tho - she seems like she could be money for the company in the same capacity as Miz is; insofar as being a great
media hand more than anything. I think her and Peyton just settling in as the women's version of Miz & Morrison is honestly their career peak, but considering how Mizanin did for himself... that's not too bad
