Los Angeles, January 31, 2008 – You wouldn’t know it to look at her, but Jessica Alba was a bit under the weather at the premiere of her new horror thriller, The Eye, on Thursday – we overheard her tell someone who greeted her not to get too close.  But not only did the pregnant Fantastic Four star look great, we finally got a close up of her diamond ring!  Alba is engaged to Cash Warren, with whom she is expecting her first child later this year.  Alessandro Nivola and Parker Posey costar in The Eye.
