Kim Kardashian must have forgotten her fancy house and car when she told Piers Morgan that the most expensive thing she's ever bought for herself is a watch.
Unlike her sister and reality-show costar, Kourtney Kardashian is not a fan of the extravagant bling, which she calls "vulgar."
Then again, Kourtney claims, she has less cash to spend than her younger sister.
"I don't have as much money as Kim," Kourtney says in the interview, airing Thursday on Piers Morgan Tonight.
Kourtney says she doesn't really purchase huge gifts for herself-- baby Mason 's future and college and expenses take priority over bling--but reminds Kim she bought a pricey "watch for yourself."
"It's vulgar," she says of her sister's $115,000 timepiece.
And it's definitely more functional than a million-dollar birthday cake.
