Ashton Shields A Vampirish Demi

So this is how she stays so young looking! She's got a six-foot-three sunshade!

Ashton Kutcher protectively shielded his older wife Demi while leaving a lunch date in Hollywood yesterday.

Ashton's new movie, Killers, starring Katherine Heigl, came out yesterday, and we bet it's Demi who's going to be shielding Ashton this weekend -- from the bad reviews!
