Bosses have apparently told the singer that ending her relationship with the dancer is the first step she needs to take in order to become a star in the States.
A source told the Sunday Mirror: "TV executives are thinking that if she's going to win over Hollywood, she'd be better off doing it as a sassy and single girl-about-town. Derek may be dreaming of worldwide stardom but he's seen as a small-time dancer on a TV show and pretty uncool."
Simon Cowell is apparently recommending high-profile eligible bachelors for Cole to date. She will also transform her image with the help of a style consultant and fitness guru to the stars Tracy Anderson.
"Everyone knows being on TV puts a few pounds on you, so Cheryl is keen to get back to her normal trim figure so she looks in perfect shape for US viewers," the source added. "Cheryl is desperate to make it in the US and producers are keen to help her become a star."
A close friend said that Cole is "torn" over the demands to split with Hough.
It was recently reported that Cole has been approached with several movie roles.
