Beyonce Knowles had to muster up all her professionalism when she performed at the Oscars in March (05) because she had to hide the fact her shoe had broken as she sang.

The DESTINY'S CHILD star performed three of the Oscar-nominated tunes and had to cope with bigger issues than just nerves when she stepped out onto the Kodak Theater stage in Hollywood.

She explains, "When I walked down those stairs, not only was my shoe not on, my ear monitor wasn't on.

"So, the song started, and I'm thinking, 'Oh God, my shoe's not done, my monitor's not on, and this is going to be embarrassing... I'm going to fall down the stairs.

"When I got to the bottom of the stairs, my shoes is off, and it's stuck in the tulle of the bottom of the dress. I'm singing on one tiptoe, and I'm trying to balance it... It was a mess."
