For the soap star, the stress and heartache of being separated from 3-year-old son Albert as she competes in the jungle is already starting to take its toll.
Throughout the hour, viewers saw Jennie grow more and more sad as she commiserated over being away from her boy with Shappi Khorsandi, who has a young daughter of her own whom she's missing.
"I really like Shappi a lot, me and her have both got little ones, her little girl is 4 and my little boy is 3," the Corrie actress explained. "We're trying not to talk about it too much, missing home and the little ones."
Jennie took time to herself to venture into the jungle, where she began weeping while thinking about the time she was missing out on with her boy.
"I got a bit teary in the loo, I was just thinking about missing home and my little boy," she admitted later in the Bush Telegraph. "It's hard to know what to talk about because if you talk about it, like now..."
As tears again rolled down her cheeks, Jennie said: "Albert didn't quite get the concept of where I was going so I said I was off to work and there might be crocodiles which he thought was really strange.
"I absolutely know Daddy and Albert will be having the best time together and they'll be having loads of fun. So yeah, I have to brave for them."
Her sadness was certainly a feeling that many viewers at home could relate to, even if they weren't parents themselves:
