Pop superstar Justin Timberlake is grateful to his ex-girlfriend Cameron Diaz for teaching him how to put life into perspective.
The 'SexyBack' hitmaker admits he is still confused by the fairer sex, despite having dated some of the world's most famous women, including Britney Spears and his current beau Jessica Biel.
However, he credits 'Charlie's Angels' beauty Diaz - who he split from in January 2007 after almost four years together - for helping him to figure out more about the female form.
He tells Britain's Cosmopolitan magazine, "I know a couple more things than I used to, but us men will never understand women. Ever!
"I think I learnt a lot from my relationship with Cameron, notably that you should always put things in perspective. As much as I've learnt though, I'm still a man, so I have some kind of learning disability. And women wouldn't have us any other way."
