Describing Lady Gaga as "very sweet", Shah Rukh Khan said the little fan in him came out when he met the international pop star for an exclusive chat during her maiden India visit.

"It (the interaction) was very nice. 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, " Shah Rukh told reporters at the red carpet of the F1 after-party here late Sunday night.

Shah Rukh wanted to collaborate with Gaga for a song for his latest release "RA.One". But the plan couldn't materialise due to time constraints.

However, he caught up with the "Poker face" singer for a chat for UTV Bindass' exclusive show.

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.

Shah Rukh came in straight from Toronto to watch the first F1 race in India here Sunday and loved the experience.

"It was very noisy, very energetic, highly energising and very well-organised, " he said, adding that he is proud of the event.

"It's a big occasion. It's quite marvellous. I think we should all celebrate the fact that we had such a big event here, " he added.
