At this point, it's easier to list all the celebrities that are NOT appearing on an upcoming special episode of How I Met Your Mother.

Reports state that Kendra Wilkinson will portray a magazine cover-version of herself on the show, which will be centered around Marshall's (Jason Segel) search for a place to read while working.

The episode - which airs in January - will also feature a trio of The Hollywood Gossip staff favorites: Kim Kardashian, Heidi Montag and Spencer Pratt.

Get your DVR ready, folks!
