I like it and it was starting to grow on me before Rihanna became popular. Unfortunately, I think a lot of people will associate the name with her, at least at the moment because she has been in the news so much and is also very popular as a singer at the moment. If I heard of a baby
Rhianna, I might think she'd been named after the singer, it would depend on the parents. Over all it's a good name.
Rhiannon is on my PNL but I actually think I prefer
Rhianna. I don't know any but there is a cute little girl on Child Of Our Time (UK tv show) called
Rhianna. She'd be aged about eight by now.
