Rihanna was spotted at Nozomi restaurant in Knightsbridge, UK after performing on the X Factor in London, and surprisingly the starlet wasn't dressed up in a costume at all! But after looking at the black tights paired with the white shoes, maybe she was a fashion don't for Halloween?

In other news, it's being reported that Rihanna has her assistants looking for a pad in London, as she's been spending a lot of time there recently. As long as she still stops by LA and NYC to visit, we're cool with it! But what about boyfriend Matt Kemp? Isn't he based in LA?
