I saw her nearly two years ago, before this last album came out. Her show at the time was bright, fun, quite campy. There was some sexual innuendo, but her outfits, while short and skimpy, aren't any different from someone wearing a bathing suit. Some low cut tops, lots of short skirts, but its not sheer, suggesting nudity. Just like a pin-up girl.
That being said, at 7 years old, I'd think a lot of her chatting with the audience would go over his head. It wasn't overly raunchy. She did pick a boy from the audience and kissed him, but not racy, just a peck on the lips. Even on her "I Kissed a Girl", she just blew kisses at the audience.
Of course, all of this may have changed since. It was a good show, though. She really did sing (no lip syncing) and the stage decor was amazing. Congrats on winning the tix! I would go see her again....
