Oops! She did it again! Britney fans flocked to her Las Vegas residency show titled "Piece of Me" on Tuesday night where they witnessed Britney fail to sing into the microphone during the song "Alien." The vocal track kept playing while Spears was distracted by her excited fans. 

Fortunately, all her fans know that she isn't singing live in the first place, so it's not exactly a letdown. All we have to say is, leave Britney alone!
