Actress Jessica Alba feels that men prefer blondes because she got more male attention after she bleached her hair for a role in 'Sin City'.

In 2005, Alba changed her brunette look and was surprised with the amount of attention she got as a blonde, thesun.co.uk reports.

She said: 'When I went blonde for 'Sin City' three years ago, I swear I've never had more male attention. I'd go to a bar and all these Arab Princes and much older men would want to buy me a drink - I'm talking guys in their 80s!'

Alba also admitted that she lost all confidence in her sex appeal when she was expecting her child with hubby Cash Warren.

She said: 'I never felt less sexy when I was pregnant! I mean, I wouldn't have changed it for the world and my cravings weren't bad - I craved citrus fruits, like lemons, oranges and grapefruits.'
