Her fans went wild for her lip kits.

And thanks to their purchases, Kylie Jenner is now a multi-millionaire, with money to splurge on the finer things.

And the 21-year-old is certainly enjoying her luxury lifestyle - showing off her mansion on Instagram.

'Good morning': Kylie panned her phone to show the stunning surroundings

Getting Labor Day off to a good start, Kylie stepped out onto her expansive balcony.

Camera phone in hand, she panned around to show her millions of followers her envy-inducing home, from the large pools to the landscaped grounds, tennis courts and multiple sun beds.

Kylie launched her makeup company, which specialises in lipstick and lip liner 'lip kits', two years ago and in that time it has gone on to sell $630 million worth of products.

She created the business herself, using $250,000 of her own earnings from modelling jobs to pay an outside company to produce the first 15,000 lip kits and things grew and grew from there, making her business worth an estimated $800 million now.

The Keeping Up With the Kardashians star welcomed her daughter Stormi, whom she has with her boyfriend Travis Scott, into the world at the beginning of February.

The businesswoman and Travis, 26, have become 'inseparable' over recent months and although they're in no rush to tie the knot, the loved-up duo are already planning for their long-term future together.
