The Atomic Kitten star entered the famous compound last night, as part of the lineup for this year's Team UK versus Team USA competition.
Ahead of launch night, she was asked if there was any previous housemate she admired for how they handled the competition.
Natasha picked Chantelle, who famously entered the Celebrity Big Brother in 2006 as a non-celebrity, but had to pretend she was famous. Memorably, she had to perform her 'debut single' called 'I Want It All' and convince the housemates that she was a popstar who had enjoyed overseas success.
She even won the show!
Natasha said: "Chantelle did really well I think. To be out with a load of celebrities and have to wing it. She showed vulnerability and I think that is something people like to see."
The mum-of-four went on to say: "You have this TV persona so people don't really know who you are. I think people will be surprised by how normal I am. It'll be nice to show my softer side because when I'm with Atomic Kitten it's all high tempo and having fun but I've got more substance than just being a girl from a pop band and it would be nice to get that across."
