Booysen appeared as a special guest on an October 12 episode of "Wide Awake Podcast," hosted by Joshua Rubin, to talk about the launch of her book and about Donaldson, who she said she had been dating.
The Twitch streamer said she met Donaldson when he visited South Africa, where she lives, accompanied by popular YouTube creators Logan Paul and Casey Neistat.
According to Booysen, the group had plans to travel to Antarctica for a video but ended up staying in South Africa for longer than they had planned, as some of the people they were tested positive for COVID-19.
Booysen said one of her friends met the group in a club, and went out for dinner with them. When Booysen heard about it, she said she decided to go and meet them all for a coffee because she wanted to find out what Donaldson was like.
"I knew of MrBeast. I knew the great things he was doing but I was also, from a psychological perspective, curious, like are these people playing it up, do they have an alter ego?" she said.
According to Booysen, Donaldson was "super nice and very down to earth" in person, and he started asking her lots of questions.
"Little did I know he was actually like going off a list, because he was looking for a new girlfriend potentially, and he had this whole list, he's like: she has to have a hobby, she has to have some interests, she has to do this and that," she said.
