Britney Spears’ Manager Confirms What We Already Knew

She promised she would be singing live during her Vegas residency, but it seems like Britney Spears may have bit off more than she could chew.

The “Toxic” singer’s manager, Adam Leber, recently confirmed to that the pop star requires some help in the vocals department for her Piece of Me shows at Planet Hollywood.

“To put on the show that she puts on, it’s virtually impossible to sing the entire time and do what she does,” Leber admitted to the website. “She’s singing on every song, basically, when she has the ability to sing. There’s no way you can dance for 90 minutes straight and sing the entire time.”

The “revelation” is not that shocking, considering the 32-year-old mother-of-two has been called out a few times since the show premiered in December.

This clip shows Brit’s microphone pack fly off with no singing interruption.

It doesn’t look like Spears’ lip syncing has hurt ticket sales, however. The pop star recently renewed her contract with Planet Hollywood, and will perform her show through February 2015.

What do you think of performers who lip sync?
