 Ken Ehrlich, a longtime producer of the Grammy Awards wouldn't confirm whether Beyoncé was a part of the show.

"Let's put it this way... we have a really great history that goes back to the early days of Destiny's Child," he said. "I love working with [Beyoncé]. She's incredible. She is so into what it is that she does and making sure that everybody who sees her walks away saying, 'wow."

"Should she be on the show this year?" Ehrlich added. "I would think that the potential is there for that kind of moment."
