'You support them every step of the way.'

Talking to Entertainment Tonight he added: 'You've got to applaud the bravery and honesty when it actually comes out of your own house.'

Chet, an aspiring rapper, who also goes by the name of Chet Haze, used social media to highlight his personal battles in a series of Instagram videos last week.

In the posts he can be seen speaking openly about drugs, as well as revealing he has been in rehab.

He says: 'I know my name has been in the media, about me going missing, getting kidnapped or something I've been in a rehab, right? I'm just trying to get my s*** together. And I'm doing pretty damn good.'

He also addresses when he decided to change his lifestyle: 'I just really had to take a look at myself and my life and the way s*** was going...and all the crazy stupid s*** I was doing, and just finally admit to myself that it wasn't working, and I had to try something new.

Open: Chet, who also uses the rapper name Chet Haze, posted a series of videos on social media outlining his struggle with substance abuse - he is seen here with his father at a NY Rangers game in March this year

'And that thing was to not do any drugs or alcohol.'

Another short shows him saying: 'All that stupid s**** I was doing, that's not who I am. That's not who I want to be, and it's been a long journey discovering who I am and the pressures that I have dealt with in my life, being the son of my dad and everything and trying to find out where I fit in.'

He continues: 'I just had to realise something, that cars, clothes, girls, guys, whatever your flavour is, that s**** is all cool, but what's really cool is being a good man, and walking with God and being a good person.'

He added: ' I am just really grateful for God, and my family, and the friends that I have, that might as well be family. It's little things that I have had to learn to really appreciate.'

Chet then advises: 'If you are struggling with this s*** take yourself to a meeting.

'Call some people, pray to God, and if you don't believe in God, conduct yourself as somebody who does and watch the miracles that unfold.'

The rapper got himself into hot water with the British authorities in June this year after allegedly causing $1800 in damages to a hotel room.

He has been battling substance abuse since he was 16 - and in November last year announced he had been 50 days sober.

The son of Tom, 59, and Rita Wilson, was also embroiled in a Twitter feud with Howard Stern, who mocked his privileged upbringing in comparison to his rapper lifestyle.

His friend Scrilla King also got involved in a dispute with Chet, and he ended his relationship with him after he used the n-word in his music.

Chet has since apologised saying: 'The truth is it's not my place to speak on that, and I am genuinely sorry for the people I have offended.'
