F1 great Lewis Hamilton kept his Ferrari move so quiet even his parents didn't know

Formula 1 great Lewis Hamilton kept his Ferrari move so closely guarded that he didn't even tell his parents until the day it was announced.

The British driver rocked the F1 world when it was announced on Feb. 1 he was joining the Italian manufacturer next year, despite signing a new contract with Mercedes last summer.

“I didn’t speak to anybody. I didn’t tell my parents till the day of it being announced. So, no one knew," Hamilton told a BBC podcast. “I really wanted to do it for myself. Ultimately, I had to find out what would be the best for me.”

It then emerged that the two-year deal penned with Mercedes and announced last August was actually for one year with an option for a second year, which Hamilton did not take.
