I think this is a total shame for this girl. I have no love for Antonella's singing abilities and I think she should be given the boot for that alone, but what a despicable "friend" for posting provocative photos (fake and real) of her online. The real ones are no big deal -- college age girls having a good time and nothing really risque. In this day of camera phones everywhere, teens snap photos of themselves doing all kinds of stupid things (i.e. on the toilet) all the time, I'll bet, never thinking they'll end up online. And the faked photos -- somebody should take that Amanda person to task. What a horrible, jealous person.
As far as underage drinking......please. Let's not cast stones when we live in glass houses. I'm sure there are some people who didn't drink when they were underage, but I'm more sure that the majority of us did. It's almost a teen rite of passage, legal or not, "acceptable" or not. It's a little disheartening in this day and age that any past unacceptable behavior you might have exhibited, or bad judgment, can be used against you if you get a little fame. Everyone's got a skeleton (or a bone or two) in their closet.
