What's with "Sally Field" name coming along "Linkin Park"?


While browsing through Facebook and Google I found that “Linkin Park” has recorded with Sally Field.
Also Sally Field was introduced along with Linkin Park in “Zack Galifianakis’ ‘Between Two Ferns’ Oscar special”.
So what is this all about ? Anyone has any idea ? Or is it just a joke !

From Mike’s twitter:

Sally Field in that show:


I’m guessing it has to do with The Mall since they are working on the soundtrack right now.
