I honestly think it's Beyonce

She is one of the best vocalists of our times, but she is also good at lipping, the few times she has done it, you can hardly tell she ain't singing live.. I always have to double check In fact I even thought to myself "god knows how many other times Bey has lipped and I've thought its live"

It's probably cuz she pre records it live and then lips over the live thingy.. This is not shade, I actually find it cool that she is the best at both live and lip

I think Britney has to be the worst at lip sync She makes it too obvious.

Mariah.

sry Brit, you're still sweet

Ashlee Simpson.

Beyoncé.

When I was at her concert — which was AMAZING, don't get me wrong — I clocked her lipsyncing at least half a dozen songs whilst my friends had no idea.

Britney lip-syncing to her 1999 vocals is the worst

Beyonce. Worst is probably Katy Perry, I remember that one Roar performance. That was tragic. Also Britney too

Celine dion

Beyonce is the best at it. She does it so often but people don't realise.

Beyonce merely for the fact that I've NEVER clocked her doing it but apparently she does so frequently

Xtina

Katy Never lips

Madonna Vogue 1990 VMA.

When did she lip-synch exactly? You're such a liar.

When Bey lips, she lips to a pre recorded track and she is very good at it because of the energy she still puts in the performance. It's not like some lazy basic bitches out there who puts on the CD and start singing along.

Now those of you who are saying she mostly lips are reaching so let's not go there.

Bey lips?

Celine is the queen of lipping, she's been doing it flawlessly for 20 years now

Beyonce always covers her mouth with her hand or her hair during the final choruses of LOT and she messed up during DIL @ the Grammys

May I send you the link to her Superbowl performance?
Or the link to the press conference where she gets asked about it and she says that "most of it would be live"?
