Oh My! Last month on Anastacia's concert I had the most embarassing moment in my life.
Before the show starts they usually play some songs to entertain the audience AND WELL, Shakira played, Hips Don't Lie...
and when I heard it starting I screamed SO SO SO SO LOUD that the all place (where 2,500 people were) got quiet and staring at me. Of course they laughed and I almost died.
Other:
Once me and my friend were at the movies and when it finished we went to the bathroom, well we done what we had to do and he (my friend) was taking a lot
then a guy entered the bathroom and I was bored and I waited for my friend outside the bathroom. I was there and I had the great idea to scare him, so I saw the door opening and I jumped and said "BAAAAAAAAAAAAAAAAAAH" and well it wasnt my friend it was the other guy who entered the bathroom next to us
I quickly turn down the music, but he had to of been in there for a few seconds to get into the kitchen. F.Y.I., the kitchen is right next to the living room where the computer is. So of course he heard me, and blabbed to my mom about it when she got home for lunch. 
I was so embarrassed, even though it was just my parents, I never let anyone hear me sing unless I'm not looking at them.
), we were doing a soul-train line during DJ Unk's "2 Step" (of all songs). Half way down the lane, someone tripped me... I never found out who did it, but I brushed it off. I've never managed to live that down, and people still think I'm clumsy every now and then
