The former Atomic Kitten star admitted that she also had cosmetic treatment in her forehead.
She told ITV's This Morning: "Do you want to know a little secret? I got some [Botox] the other day! It was amazing!"
The Celebrity MasterChef winner added: "I actually got some in my armpits to stop me sweating for filming my new series and I went, 'Oh just pop a bit in my forehead as well', and it's absolutely brilliant.
"And it's for me. I've told everybody!"
