In 2008, Dakota Fanning and Alicia Keys starred in the movie "The Secret Life of Bees" together. And meeting Keys gave Fanning an opportunity to do something she had never done before: go to a concert.

"I never went to concerts until very recently, and I was doing a movie with Alicia Keys so I went to her concert," Fanning, who hits the big screen this week playing rocker Cherie Currie in "The Runaways," told MTV News about her first concertgoing experience.

And Keys was happy to oblige. "Yes, that's true. She came to my L.A. show for my last tour and it was her first concert," she recalled on Wednesday night in New York City, where she was playing a show at Madison Square Garden. "We had just finished a movie, 'Secret Life of Bees,' together ... and I was so happy to be her first concert."

Keys added that the actress, now 16, certainly has the chops to be working in Hollywood for many years to come. "She's an amazing person, an incredibly talented lady. She's gonna be someone we watch flourish for many years. And I'm glad she will always say her first concert was me."

Also on Wednesday night, Fanning spoke about how very obedient to the rules she still is in her own life, even though she plays a wild child in her new movie. "Cherie kind of grew up with no restrictions or rules, kind of figuring it out for herself. It's kind of different for me," she shared. "I will never get to have that experience, so I kind of got to have it through the film."
