Viewers tuning into Leaving Neverland were left shocked by James Safechuck's mum, Stephanie.
The first part of the documentary, which aired on Channel 4 on Wednesday 6 March, featured Wade Robson and James Safechuck revealing – in detail – the sexual abuse they allegedly suffered at the hands of Michael Jackson.
Whilst the two men recalled how they met Jackson and what happened in the months that followed, the programme also included interviews with members of Safechuck and Robson's family.
As the cameras focused on Stephanie, she was seen giggling whilst talking about how her son would be kept in Jackson's room.
"I wanted to know what was going on in the room," she giggled.
"My son doesn't know this but I would go to the door and try to hear what conversation was going on and then I'd sneak away," she added.
However, viewers were left shocked by Stephanie's demeanour and took to Twitter to share their thoughts.
"Also, why on earth would a mum look back and laugh/smile when thinking back on when her little boy was allegedly sexually abused? #LeavingNeverland," one user shared on Twitter.
Whilst another commented: "What the hell is this mum's problem or is it just me that it's so bizarre she smiles laughs and jokes while her son talks about being sexual abused, violated and raped this is extremely tough to watch #LeavingNeverland."
"What the hell is this mum's problem or is it just me that it's so bizarre she smiles laughs and jokes while her son talks about being sexual abused, violated and raped this is extremely tough to watch #LeavingNeverland," a third user of the social networking site shared.

A different tweet read: "Why is the mum laughing so much? LeavingNeverland."
The documentary, which concludes on Thursday 7 March, sparked a debate about who was telling the truth.
However, Leaving Neverland's director Dan Reed defended Jackson's accusers when he told Piers Morgan on Good Morning Britain recently that he didn't think Robson and Safechuck were after money.
"No, they want justice, they are not fussed about the money. I don't know what they'd do with the money when they get it. They're entitled as citizens to use the courts to hold the Jackson estate – and their contention is that all these people who worked with Jackson looked the other way while they were being raped."
Leaving Neverland continues on Channel 4 at 9pm tonight.
