Blu Cantrell, whose birth name is Tiffany Cobb, got her nickname "Blu" from her mother when she was little. It's said that Tiffany's mother always called her Blu as a child, and it just stuck with her.
We're guessing the name "Blu" comes from the singer's eye color, but there could be more reasons than one.
When it was announced that Jay and Bey named their first born child Blue Ivy, Blu Cantrell's Twitter was flooded by fans wanting to know how Blu felt about the name choice.
