Cole not keen to imitate Rihanna

London: Singer Cheryl Cole confessed she wouldn`t be able to be as blunt as Rihanna. "Rihanna is a free spirit and doesn`t care if she calls somebody a **** on her Twitter. But there are 12-year-old girls on there," femalefirst.co.uk quoted Cole as saying. Cole, whose parents separated when she was 11, insisted that she prefers to be nice to people and set a good example to youngsters. "I didn`t grow up with a role model so it`s nice to be somebody`s guide," she added. IANS
