We told you that Beyonce lip syncs most of her songs due to the fact that she’s out of shape and tends to lose her breath a lot. But we never really had sufficient evidence to prove our case until now!

Peep this video of Beyonce’s last performance in London last night. She brought pop icon George Michael onstage to perform a duet of her song “If I were a Boy.”

Watch Bey’s face at the 35 second mark as she realizes she FORGOT to sing along with the track!

She tries to play it off by mouthing the words but TOO LATE! The mic is nowhere near her mouth!! You can clearly hear Bey’s voice as she LOOKS DOWN in shame!

It feels great to be vindicated for once! :D
