Alba: 'Men are easy to manipulate'

Jessica Alba has revealed she hasn't appeared naked on screen yet because she finds it easy to manipulate men.

The actress has posed in photoshoots for lads' magazines including Maxim and Arena but has never appeared naked on screen.

"Men are visually stimulated," the actress said in an interview with The Times. "They are easy to manipulate. All you have to do is dress up in a sexy outfit."

The 26-year-old, who played a stripper in 2005's Sin City, admitted she is wary about making friends in Hollywood because of her looks.

"If anyone gets too friendly too quickly, it feels wrong," she said. "I have to ask myself if I want to let them in to my life. Or, why should I?"

Alba is expecting her first child with fiancé film producer Cash Warren later this year.
