Being single is not cool : Rihanna

London Pop star Rihanna, who recently denied reports that she is dating boxer Dudley O'Shaughnessy, says that it is "not really that cool" being single. "I'm not dating anyone right now. I'm not dating at all. I'm not necessarily happy being single. It's not really that cool, " quoted the 23-year-old as saying. "I do put a lot into my job - most of my time if not all of it. It definitely affects my personal life," she added.
