Her reason?

“Due to the weather, due to the delay, due to no proper sound check, I did not feel comfortable taking a risk. It was about the president and the inauguration. I wanted to make him and my country proud,” she said. “I decided to sing along to my pre-recorded track, which is very common in the music industry.”

Beyonce started her Superbowl news conference with the singing of the National Anthem. At the end of her singing, she asked “any question?”

The first question was about her performance at the inauguration, and whether or not she lip synced. She answered, “I am a perfectionist and one thing about me, I practice until my feet bleed and I did not have time to rehearse with the orchestra,” she said, explaining her decision to go with lip synching. “I am very proud of my performance.”
