The housemates voted her out and decided to keep Alistair instead.
She said: "It was so nerve racking - every time I had to get on that stage I would just start shaking, but I am going to keep going. I want to record an album of my own songs."
Louise had been the favourite to get kicked out this week.
The 25-year-old singer-songwriter from Hertfordshire added:
"I would like to see Paris and Alistair again as I really enjoyed writing with them and I hope we get to continue writing together."
