Caitlyn Jenner -- Check Out My New Killer Curves (PHOTOS)

Caitlyn Jenner has something sexy, new and Italian to flaunt ... her custom made exotic sports car.

Caitlyn had her tricked out Lambo Aventador delivered by flatbed truck to her Malibu home early Tuesday. It's a pretty Kardashian-esque purchase -- remember, Kanye's got one of his own. Base price is $400k, so you can bet this bad boy ran her more like half a mil.

Sorry, Caitlyn but we already see trouble brewing. Getting in and out of a Lambo in a pencil skirt can't be easy!
