Kylie Jenner plans to invest in real estate.

The 17-year-old reality TV star - who's openly expressed her desire to move out of her family home when she turns 18 in August - is already working out the best way to invest her ever-increasing fortune and her mother Kris Jenner, 59, has pledged to support her youngest daughter ''every step of the way''.

In a new episode of 'Keeping Up with the Kardashians', Kris explained: ''Kylie reminded me that she had a lot of projects that she's been working on and she really wants to take that money and invest in real estate. I think sometimes Kylie is underestimated, because she really is a bright kid.

''I just want to be here with Kylie every step of the way.''

Recently, Kylie suggested that being exposed to fame at such a young age has caused her to grow up ''a lot faster'' than her peers.

The TV star - whose 19-year-old sister Kendall is a catwalk model - said: ''It's definitely been crazy. I've been through so many situations that people my age don't go through. It's made me grow up a lot faster.''
