Lip syncing is the thing when famous celebrities just get too busy to even prepare for a live moment of performance. But what happens when the event is actually is held live but the only thing that isn't is their voice?

Here are picked videos of artists who have been caught in the act of lip syncing at the wrong timing:

Katy Perry on Playing the Flute

Yes, Katy Perry is one talented lady, but not when it comes to playing the flute. Besides, she does not have to show off much more for as long as she bats her eyelashes perfectly well, every performance she will make will still remain as bouncy as her personality each and every time.

Lindsay Lohan in 'Good Morning America'

No one can deny how much LiLo once was such a cute and adorable singer and the lip syncing fail in this video is not that all messed up but if you would look closely, you would surely notice that it was not at all good still. It was just easy to tell that it was not her voice that you are hearing. It sounded amazing only if she did not miss on the syllables.

Britney's Failed Comeback Performance

With her being in the group, it was very easy to detect her slight mistakes and how she appeared very tensed and all nervous with this performance. This served to be one of her most controversial videos that was supposed to be a successful comeback performance. It was just all too slumpy she poorly mouthed her lines without life and energy.

Shakira

Even if she has worked hard so much for Africa, it is still not cool to have discovered her lip syncing some of her booty shaking performances like this one. It is way much better to convince others to help Africa if her live performances would be better crafted.

Lady Gaga

It can be frustrating to know how the most energetic artists on stage are discovered to be lip syncing some of their songs just like Lady Gaga. To think that she has already gone on record that she never does any lip syncing. So what is this about?
