He was an F1 star, 7 time world champion. You were a singer, who was popular because of the songs with a lot of touching lyrics.
You were resting with your friends in Miami, one of them decided to buy tickets to the paddock on the race. You never were interested in F1, you heard about it a couple of times of course, but you were completely clueless about it. You only knew how F1 car looks.
So as you enter the paddock some paparazzi catch your familiar face, already knowing who you are. It just so happened that you entered the paddock at the same time as Lewis himself. You didn't notice each other.
Only in the Ferrari garage, when he was checking on his car you were looking around, listening to someone. You accidentally bump into him.
"Oh sorry." He says quickly, but then he notices her face recognizing her. "Hey aren't you that one singer that got a Grammy for the best album of the year?"
