Why would I? That's not her name XD Thought I read pretty often when people call her like that XD

She IS (subjectively) a sleeping beauty, but that's the title of the movie, and at most, a nickname for Aurora. I remember Phillip call her "my sleeping beauty" or something along those lines in Enchanted Tales (which is mostly considered non-canon).

Only when I'm talking about her with people that don't know much about the DP's, because they tend to not know her actual name, so I do it to avoid confusion. xP

Only if I'm talking to someone who doesn't know much about Disney since they aren't likely to know her name, but even then pretty rarely.

What NCISLuverjk93 said.

If I called her anything else, it would be Briar Rose.
