The former 'Apprentice' star has been linked the series, despite previously hailing it as "s**t and embarrassing".
The Sun reports that Luisa will be among the famous faces entering the house when the latest run of the Channel 5 show kicks off on Friday.
A source told the paper: "Luisa is determined to sex up the house and bring some fun to the show.
"She was in the running last summer but didn’t make it."
However, when Luisa was last linked to the show, she tweeted: "More importantly no I don't want to do celeb BB it's s**t and embarrassing."
"My main focus is my business!" she added, having recently launched Bakers Toolkit - the business idea she originally pitched to Lord Sugar on 'The Apprentice'.
