Crazy in love: Beyonce and Jay-Z, the intensely private power couple

There was a rare public declaration from the chanteuse at the 2010 Grammy Awards.

When she was called to the stage to collect the Best Female Pop Vocal Performance award she said: "I'd love to thank my family for all of their support, including my husband. I love you."

And what was her husband's reaction to her acceptance speech? "He was shocked! He was just like, 'What did you say?'

Beyonce, who eventually went home with six Grammys, said she was just lost in the moment. "I was so happy, I could've said anything. That's why I ran off the stage," she explained.

"I just looked up, and he was the first face I saw. And I was like, 'What did I just do? No, I didn't just say that'"
