After singing the national anthem at the Super Bowl, Destiny’s Child star Beyonce Knowles told The Early Show’s Hannah Storm about how she just wanted to do Whitney Houston justice. “I was so nervous before I sang the song,” Knowles admitted. “My heart, I could see it beating out of my chest, because this has been a dream. And I have been telling my mother since I was, I don’t know 8, 9, ‘I’m going to do that.’ Every year I saw someone singing, ‘I’m going to do that.’ And she was like, ‘OK, baby. All right’.” Watch the interview online at CBSNews.com.
