Beyonce 2014 Grammy's lip sync: 'Drunk In Love' slip up, Jay Z and Beyonce PDA, Blue Ivy's sippy cup [VIDEO]

Beyonce Knowles is caught in another lip synching scandal after her epic Grammy's performance with her husband Jay Z. The Carter's opened up the Grammy's with their latest collaboration on "Drunk in Love" and the performance seemed to be authentic until Beyonce was caught missing some vocals playing live as she pulled her mic away.

 Towards the end of the performance Beyonce made up for the lip synching and busted out live vocals standing next to her husband getting touchy as they displayed the same behavior throughout the night.

Jay Z was caught dancing with his wife throughout the night and expressed his feelings to his wife when he won a Grammy for Best Rap Collaboration for 'Holy Grail' with singer Justin Timberlake.

"I want to thank God a little bit for this award but mostly for that and all the universe for conspiring to putting that beautiful light of a young lady in my life," He continued to thank another special little lady saying, "I want to tell Blue, Daddy got a gold sippy cup for you."
