Sheryl Crow has had a pretty long music career and has performed many times throughout the years. All that considered, you'd think she would remember the words to all of her songs, especially the more popular ones!  But that didn't happen during a concert over the weekend.

Sheryl was putting on a show in St. Petersburg, FL over the weekend and when it came to performing her song "Soak Up The Sun" things were going along fine and then all of a sudden she couldn't remember the words to the song. TMZ.com got their hands on the video in which Sheryl says, "Oh, what's the words?" and then goes on to say, "I'm 50, what can I say! My brain has gone to s**t!"

Catch her flub below and just for fun, you can learn the words from the actual video that goes with the song!
