Celebrities really are just like us: They sing to life-size cardboard cutouts of Robert Pattinson, too.

This pop singer was performing at her concert last night when a fan handed her a huge cutout of R.Pattz.

The celeb, who got her start on American Idol, proceeded to serenade the cardboard version of the world’s hottest vamp.

It’s Kelly Clarkson.

You can check out her performance of “I Want You” to the poster-size R. Pattz here!
