Kendall Jenner drinks 12 cups of detox tea every day.

The 18-year-old model admits she is a huge fan of hot cups of lemongrass and green tea flavoured Kusmi Detox Tea and credits it for helping her to stay slim.

The 'Keeping Up with the Kardashians' star told E! News: ''I usually start my day off with a cup of detox tea. I have like 12 cups a day.''

The brunette beauty, who is currently working at Paris Fashion Week, also snacks on apples and sticks to a clean diet of lean protein, fruit and vegetables to make sure she has enough energy on the catwalk.

Kendall also enjoys working out, but rarely has time at the moment.

She said: ''I like running. I've been trying to get back into it.''

But her top beauty tip is to get enough sleep.

She said: ''My beauty secret for fashion week is just getting a good amount of sleep. I feel like I at least need about seven hours, eight hours of sleep to function.''

Kendall is in Paris with her mother, Kris Jenner, half-sister Kim Kardashian West, brother-in-law Kanye West and 15-month-old niece North West, who are expected to support her by attending at least one of her upcoming runway shows.
