Pregnant actress Jessica Alba is counting her lucky stars after suffering a terrifying tumble backstage at the Academy Awards on Sunday (24Feb08). Alba, who is in her third trimester, was caught just in time by fiance Cash Warren. And the 26-year-old Latina is astonished normally eagle-eyed photographers missed the whole thing - because she fell right in front of them. She writes online, "I did have a stumble backstage outside of the green room. Cash caught one arm, the other hit the floor. "Luckily all the photogs were taking pics of Cameron D." Gossips claim Alba will give birth to twins later this year.
