Kourtney Kardashian debuts blonde makeover

Kourtney Kardashian has debuted a new platinum blonde hairstyle.

The reality TV star took to Instagram over the weekend to share a slideshow of snaps in which she showed off her new blonde bob while posing in a leather bustier top.

In a separate post, Kourtney shared several photos of her sitting at a casino in Las Vegas.

"Every now and then when your life gets complicated and the weasels start closing in, the only cure is to load up on heinous chemicals and then drive like a bastard from Hollywood to Las Vegas ... with the music at top volume and at least a pint of ether," she wrote in the caption, quoting Hunter S. Thompson's 1971 novel Fear and Loathing in Las Vegas.

In response, Kourtney's sister Khloé Kardashian wrote, "I have no idea what this caption means, but I love your hair with a side flip!"

As part of her post, the mother-of-three credited hairstylist Glen Coco Oropeza with transforming her signature brunette tresses.

She also shared two sources of inspiration for the look on her Instagram Stories - a snap of Drew Barrymore in the '90s as well as a throwback photo of herself with dyed blonde locks as a teenager.

"Seventeen-year-old Kourt... strikes again," the 43-year-old captioned the photo. "Bored during finals, convinces someone to dye my hair blonde to procrastinate."
