She told W magazine's February 2013 The Movie issue: "I love Ryan Gosling! I met him at the Governors Ball after the Oscars two years ago, and I freaked out.
"He stares into your soul. He's really tall, and the boys in my grade are all shorter than I am. He was looking down at me, which was a first, in a weird way. He shook my hand and said, 'It's so nice to meet you'."

The younger sister of Dakota Fanning - who will celebrate her 15th birthday in April - admitted that she wanted to give him a kiss but couldn't bring herself to do it.
She lamented: "I didn't kiss him goodbye. I didn't have the confidence."
