Rebecca Black can sing a bit. She is a third class singer lets face it! The song is catchy but I guess anyone could have sung it with the help of autotune. Though I am not saying she can not hit a single note. The lyrics are far too shallow even for this type of song.
The make-up unflattering maybe even a bit sluttish. The video is like: „Sorry, we did not have enough time to make a good one!“.
