When Julia Roberts was called onstage at a Taylor Swift concert, she was not prepared.
Roberts, 48, talked about her epic night dancing alongside Swift and Joan Baez on the singer's 1989 tour stop in Santa Clara, California, admitting that it was a last-minute decision for her to take the stage.
"I will say this about my outfit, is that I had about five minutes' notice that I was going onstage," she said while appearing on The Ellen DeGeneres Show on Thursday. "I didn't dress for 50,000 people. I smelled nice and that was the whole point."
