Kendall Jenner's got a sweet new ride -- and it's definitely not what you'd expect from the 20-year-old "Keeping Up With the Kardashians" star. Just one day after her birthday bash, Jenner was spotted cruising around Beverly Hills, California, in a gorgeous whip with her close friend Haley Baldwin by her side, leaving many to wonder if the car was a gift.

As was reported by E! Online, Kendall and Baldwin, 18, were seen driving around in the robin's egg blue and white Chevrolet on Tuesday. They were reportedly heading to the Beverly Hills Hotel for breakfast before meeting the rest of their crew for a hike. Beverly Hills Car Club owner Alex Manos told the publication that, while it was unclear if the car was gifted to Kendall, it was definitely not cheap. He claims a 1957 Corvette in that condition would generally sell for around $100,000.

"This particular model 1957 Chevrolet Corvette Convertable comes in Cascade Green with beige coves and white shoreline beige interior and beige soft top," he said. "It's a 4-speed care and should come with the spare tire, jack, jack tools and trunk mat. The tires are the original white walls. This is a great example of the first generation Corvette."

Kendall, who recently announced that she would be walking in the 2015 Victoria's Secret fashion show, celebrated her birthday in style Monday. She invited all her closest friends, including fellow model Gigi Hadid, sister Kylie Jenner's boyfriend Tyga and ex-boyfriend Jaden Smith, as well as her entire famous family to a party, according to TMZ. The party took place at The Nice Guy in West Hollywood, which also played host to Kylie's 18th birthday party in August.

During the party sister Kourtney Kardashian let loose -- literally. The "KUWTK" star is said to have suffered a wardrobe malfunction while dancing the night away at her younger sister's party. She was wearing a fitted lace-up corset, which E! Online reported was slightly see-through. Kourtney, 36, layered up with a chic jacket on top, but with one false move her entire top half was exposed.
