Naming your child the same thing twice

Has anyone else seen this as a trend lately? I have and I personally don't like it at all. For example Bella as a first name and Isabella as a middle name "Bella Isabella" or "Audri Audrianna" or "Aaliyah Leah" obviously it's not my business what people decide to name their kids, I just could never do that to my own...anyone else agree with me or do you like this little "trend"
