Christina Aguilera is one of the most powerful and talented singers around, but every person has a down week and this past week seemed to be Christina's.
Christina started off last week singing the National Anthem at the Super Bowl and immediately caused chatter as she mixed up some of the words. She then appeared last night at the Grammys where she performed in a tribute to Aretha Franklin.
After the tribute, she helped present an award and had a little tumble on stage. In our opinion, if we had to walk on stage in heels in front of millions of people, we'd probably wobble too.
Despite all those things, Christina's voice was still flawless at both events.
Do you get nervous when you speak or perform in front of people?
