Kim K's Most Expensive Purchase: $115,000 Watch!

Dayum.
On Thursday night’s Piers Morgan Tonight Kim and Kourtney Kardashian stop by and talk about their spending habits.
Kim tells Piers the most expensive thing she ever bought was a $115,000 watch, but she got a really good deal on it:

“I traded two in for it, so, technically I was out of pocket about $50 or $60,000.”

We’re sure The Brissmor Company, who developed Kim’s very own watch collection, will be thrilled to hear that.
So what does her sister think about Kim’s lavish spending?
Kourtney says:

“I don’t have as much money as Kim. I don’t think I could ever just go and spend that, you know? I don’t do that stuff for myself. It’s vulgar. And I have a baby that I’m, like, college and expenses├óΓé¼┬ª.”

Bitter, much?
