(CNN) -- One of the three women held captive for nearly a decade in a Cleveland, Ohio, home, made a public appearance Saturday at a concert.
Amanda Berry, along with members of her family, got onstage, surprising concertgoers at the daylong music festival Roverfest. Berry didn't speak onstage, but she smiled and waved to the crowd.
"I told her she had a little bit of time to make up on the partying and you guys would help her out tonight," radio personality Shane "Roker" French told concertgoers.
Berry later returned to the stage, where rapper Nelly dedicated his hit song, "Just a Dream," to her.
Her appearance came a day after Ariel Castro pleaded guilty to 937 counts in connection with keeping Berry, Georgina "Gina" DeJesus and Michelle Knight captive inside his home. Under the plea deal, he will spend the rest of his life in prison without parole.
Castro, who originally faced 977 counts, abducted the women in a two-year period starting in 2002.
The three women released a YouTube video earlier in July, thanking people for their well-wishes and support.
