That seems innocent enough as long as she didn't actually flirt or touch him affectionately during the interview. Most teen kids use the word "hot" to describe someone who is more "cool and cute" compared to the old definition of "hot" which used to mean "sexy". The woman was just trying to act hip and young while she said that compliment to him.
What his name?
vacuous inappropriateness is what modern media is built on
rather than getting your knickers in a knot on that one, start from the top of the tree
She likes young boys.
Maybe it was hot and she was asking if he needed the AC turned up
YES, that's very creepy and borderline illegal because it seems like the woman was flirting with the kid.
What celebrity is that???
