'I would have washed my hair if it had been planned'

Julia Roberts surprised Taylor Swift fans when she appeared on stage with the star during Swift’s 1989 tour stop in Santa Clara, California. As the guests of the night, Roberts and Joan Baez danced around the stage in Taylor Swift T-shirts, thereby becoming part of Swift’s elite (and ever-growing) list of tour guests.

Now, in a new interview with Extra, Roberts explained how she ended up on stage with Swift and Baez. When asked if it was planned, Roberts said, “No! Oh my God, I would have washed my hair if it had been planned. I was wearing a ponytail, leggings, and tennis shoes.”

She said she had taken her three children to see the show at Santa Clara’s Levi’s Stadium and met Swift backstage beforehand. “They had never been to a concert before and they were big fans,” she said. Then, Swift asked Roberts to join her on stage. “She said, ‘Would you mind coming on stage during the song and dancing?'”

Roberts said she remembers asking her children what they thought of the proposition. “‘Oh, Mom you have to do it!,'” Roberts said, imitating her children. “My youngest son said, ‘Only do it if you want to, Mommy.’ It was so sweet!”

When asked to recall the performance, she told Extra, “It was one of those crazy, out-of-body moments. I can’t tell you anything that happened from the moment I came on stage. I was so nervous.”

Yeah, we’d say she did okay.
