He About To Lose Me is the one single I can see her promoting the most, it doesn't require much but a backing track and a simple performance. She can do theatrics if she wants, but "ballads" are the easiest thing to promote
.....Britney is under no obligation to hug people. You meet, and greet. A greet is a handshake, a hello, a wave. Do you hug strangers you're just meeting? Probably not. Give her a break. You pay to meet her and take a photo. You're doing something millions of other fans haven't done. Shut the **** up, quit complaining and DEAL with her being uncomfortable hugging people.
