A former Puma endorsee, Kylie Jenner has announced that she was switching Adidas, to help market the Falcon sneaker. The reality TV personality shared the news on social media, wearing a pair of Falcons, part of the Adidas Originals range. Jenner's switch to Adidas reunites the family: Kendall Jenner, Kylie's sister, has been with Adidas since May; and Kanye West, her brother-in-law, is an Adidas partner with the Yeezy range. Kylie Jenner appears to be particularly astute at turning her TV reality fame into business, since she featured on the cover of the issue of Forbes magazine containing the ranking of the 60 richest self-made Americans – with a fortune estimated at no less than $900 million. This is chiefly due to her more than 111 million Instagram followers and her cosmetics business. Forbes reckons the 21 year-old could turn into the youngest ever self-made billionaire, ahead of Mark Zuckerberg, who reached that threshold at the age of 23.
