(Newser) – Rihanna got the rumor mill going when she was spotted wearing a large diamond ring over the holidays, the Daily News reports. But boyfriend Chris Brown's rep says the two aren't engaged. The couple have dated since 2007, but Rihanna is tight-lipped on their relationship: “People always want to know what it is and what it isn't. People think they know. They try to guess,” she said on The Ed Lover Show last year.
