Jessica Alba has revealed there is often more than just acting going on when it comes to the love scenes being filmed on movie and television sets across the globe.

The gorgeous actress has discovered a disturbing number of people get tangled up in short-term whirlwind romances, cheating on loving partners back home, for as long as the filming lasts on location.

But despite herself being one of Hollywood’s sexiest stars, the pregnant actress insists her fiancé Cash Warren has nothing to worry about – as far as her remaining faithful is concerned.
