The 17-year-old's Grammy-winning song was not influenced by kings or queens, but rather a photograph of an athlete she had seen in a magazine.She told VH1: "I had this image from the National Geographic of this dude just signing baseballs. He was a baseball player and his shirt said, 'Royals'."The picture featured former Kansas City Royals player Brett surrounded by fans holding up baseballs for him to autograph.During her visit to Las Vegas, where Lorde performed on Tuesday, she met the sportsman who helped launch her international career.The get together was captured on camera and the snapshot was posted on the official Major League Baseball Twitter.com account on Wednesday, alongside the caption, "And now you're Royal. @lordemusic meets @Royals icon George Brett."Now Brett is a big fan of the singer, telling TMZ.com: "Lorde is such a sweet little girl. She's only 17 years old and she's very talented... I actually downloaded her music off iTunes and listened to it on the plane ride to Vegas. I knew all the songs when she sang them."He adds: "My wife and I met her after she did her soundcheck. And then we got to talk to her for a little bit after the concert also... We both said it was nice to meet each other."
