"Cheryl wants to make her show as amazing as possible and if that means spending a load of cash on it, so be it. If it were a longer tour, she would make money back from ticket sales. But the ideas she's coming up with at the moment are not going to come cheap," a source said.
Cole will play 11 dates in the United Kingdom in October, starting in Belfast, Northern Ireland.
There are a few themes she's working on, taking inspiration from shows by Katy Perry, Rihanna, Jay-Z and Kanye West.
