Pop hunk Justin Timberlake has refused to surf with girlfriend Cameron Diaz because he has a severe shark phobia stemming from his childhood.
The Justified singer, 23, moved to Florida when he was eight years old to film the Mickey Mouse Club TV show - with former girlfriend Britney Spears and Christina Aguilera - and was deterred from swimming in the sea after a spate of shark appearances.
Timberlake explains: "We started going to Coco Beach every weekend. All of a sudden sharks started to attack. I was afraid to go back into the water."
