Britney gets picked on all the time, and I don't like it. I don't know why, I just feel motherly toward her and I hate when the press picks on her. So she fell during her concert and her heels aren't high, so she didn't fall for that reason. She fell because she zigged when she should have zagged. Lots of us have done that, without the annoying feature of being filmed most of our lives.
My daughter said Ariana Grande tripped while in concert here, and she just got back up and played it off. Poor Britney twisted her ankle, so that pop back up wasn't happening. But look at Ariana's heels. Those are serious falling shoes, so good for her for plopping back up.
We really need to stop going after celebrities for every little slip-up made. They are human and how can you do a live concert every night and not have a mistake? Look how many editors a book will go through and there may still be a typo. Life happens.
