During their first week in camp, tensions grew between Nella and Fred after a conversation about their ages hit a sensitive subject for the YouTube personality.
While the First Dates star was cooking a meal for the group, he told the 26-year-old that, at 51, he “could be your dad”.
Nella’s father died in 2020, and a day after her exchange with Fred, she confronted him to say she thought he’d been “disrespectful” towards her.
“Don’t bring up my dead parent, are you stupid?” she told him, before branding him a “weirdo” later in the conversation.
On Monday night, Nella became the latest contestant to leave camp, and was asked about the row during her exit interview by hosts Ant and Dec.
“I just feel like in the middle of an argument, or in the middle of a disagreement, you shouldn’t bring up sensitive topics,” she told the pair. “I feel like, in the middle of a disagreement, he brought up a sensitive topic. I didn’t understand why he would do that.”
Asked whether there could have been a misunderstanding, Nella responded: “It could have been, but things are so heightened in the jungle that everything is a big thing.
“I’m not usually put in situations where I’m around people that don’t have the same kind of walk of life as me. So, when they have different mindsets, and I hear them, I’m shocked because I’m like, ‘People think like this’.
“I automatically have to say something about it, because to me it’s just kind of shocking sometimes.”
Just eight contestants remain in the current series of I’m A Celebrity.
I’m A Celebrity continues on Tuesday night at 9pm on ITV1.
