Where does the child seat go? Easy rider Scott Disick leaves Kourtney holding the baby as he takes his motorbike for a spinOn tonight's episode of Keeping Up with the Kardashians, Rob Kardashian questioned his sister's partner Scott Disick's parenting skills.
But despite this, the reality star made little effort to ditch his bad boy reputation and look like an ideal family man today.
Just hours before the episode aired in the US, Scott rode his motorcycle around Malibu, leaving Kourtney to trail behind him in a car with their baby Mason.

'The reason I don't come over here is because of Scott. He's an alcoholic! He's a negative person in my life. Like, [he] has a kid,' Rob said in the episode.
'When he punched the mirror in Miami, he showed his true colours, and I pretty much haven't spoken to them since that night.'
'Show me that you're mature and show me you're mature enough to have a kid with my sister.'

And in the previous episode, she admitted that the reason she has always turned down Scott's proposals of marriage is because she's not absolutely sure he is 'The One.'
The 28-year-old entered therapy to treat his addiction late last summer after constant fights with Kourtney.

'But now that I have a little baby, I don't really want to play any of these games. I just want to be with her and see my son grow.'
