Reality stars to appear on 'HIMYM'

LOS ANGELES, Nov. 13 (UPI) -- Kim Kardashian, Kendra Wilkinson, Heidi Montag and Spencer Pratt have signed up for guest spots on "How I Met Your Mother," CBS announced Thursday.

The episode is in production and expected to air in January, the network said, adding that the reality television personalities 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."

Kardashian, Wilkinson, Montag and Pratt will "taunt and tease Marshall from the confines of his current copy of Them Weekly," CBS said.

The sit-com co-stars Josh Radnor, Alyson Hannigan, Neil Patrick Harris and Cobie Smulders.
