Shah Rukh Khan has millions of fans, but even he was starstruck when he finally met Lady Gaga ahead of her Formula One concert in New Delhi on Sunday. "It (the interaction) was very nice," Khan told reporters on the red carpet at the F1 after-party.

"She (Gaga) was very sweet. I sat with her for a couple of hours and exchanged a lot of good things about life. She is very deep, very sweet," Khan said. The 45-year-old says he became a Gaga fan thanks to his daughter, Suhana, 11.

"My daughter is a big fan of Lady Gaga. She listens to her music and introduced me to her music, and I am also a fan of her now," he said. During her performance, Gaga, who had promised to add an Indian element to her show, played the piano alongside a sitar player at the concert at Jaypee Greens Golf and Spa Resort in Greater Noida.
