Rhianna is definitely the same as Rihanna to me, and I'd always associate the two. It sounds trendy and a bit like celeb worship. It's not a "bad" name (I save "bad" for names like
Adolf), but it's not a "good" one either. It lacks class and won't age well. Besides Rihanna being abused by
Chris Brown, I'd still say it's a no-go.
