London, Feb 21 : Leona Lewis has said she would love to sing at TV mogul Simon Cowell's wedding.

The `American Idol' judge is presently dating hair stylist Mezhgan Hussainy.

"I performed at his birthday party so he may ask me again. I can''t wait to speak to him, I''m shocked. I really didn''t think it was true. But Mezhgan is absolutely lovely," the Mirror quoted Lewis, as saying.

She added: "I''ve met her a few times when we''ve been in LA and they''re a really nice couple."

Lewis' Labyrinth themed tour is coming up in May. (ANI)
