Zoe Saldana Marco Perego PAris Rosemary's Baby Zoe Saldana Marco Perego PAris Rosemary's Baby

These two can't keep their hands off of one another!

On Saturday Zoe Saldana and her husband Marco Perego arrived at Los Angeles International Airport, and before they headed to their chauffeured car, they shared a sweet smooch in the terminal. We're not sure what they were talking about, but once they got in the Marco shielded his lady love's face from photogs.

Is there a reason he's acting so protective? Like...does Zoe have a bun in the oven and his paternal instincts are kicking in? Or is he just really attentive? After all, we did snap him carrying her Chanel purse in Italy a few days ago...
