Montag and Pratt will each film their segments this week.
"We can confirm that Heidi and Spencer will appear on the show, but we can't give away anything specific about the episode," Co-creator and Executive-Producer Craig Thomas said. "All we can say is that they play themselves."
However, CBS' statement revealed a bit more about the episode, stating that Montag and Pratt "will be playing magazine cover-versions of themselves as Marshall (Jason Segel) desperately searches for a place to "read a magazine" while at the office," according to Us. "Montag and Pratt will taunt and tease Marshall from the confines of his current copy of Them Weekly."
