Thats one of the few things that does irritate me, it appears to be a bit of a habit now, (that under the chin thing)Agree entirely. I used to have a body like NNL's when I was her age but would never have done what she does (of course now I'm in my 50's I actually do have the belly!). And also, that hands-beneath-the-chin pose is very unbecoming!
My 6 year old godaughter does this as part of her ballet dance class routines along with a little curtsy. . Super cute except she’s dressed in a tiny tutu and she is in primary school. It’s very Disney princesses.
