Kim Kardashian: I've Already Bought the Ring

Somehow celebrity Kim Kardashian says she's already bought the engagement ring for when football star Reggie Bush pops the question.
"He definitely knows all of us went ring shopping," she said recently on Sirius Radio.
Kim has no qualms about taking the initiative and going out and buying an item that secures her love forever.
"I definitely scared him and told him it was probably way more expensive than it is, just so that when he goes he feels like he's getting a good deal," she said. "He knows what it looks like. I think I-ve e-mailed him enough pictures."
Is this kosher, ladies?
Should you buy a ring for your gent without so much as a conversation? And even if there was conversation, would you be secure a enough to drop several thousand?
