Maybe Kelly Ripa should have just dressed up as a fortune teller.

The LIVE! With Regis and Kelly mainstay joined guest cohost Nick Lachey for her morning show's annual Halloween-themed broadcast Monday, and took the stage outfitted as Kim Kardashian on her wedding day -- just hours before news broke that the 31-year-old mogul filed for divorce from Kris Humphries.

Not to be outdone, Lachey, 37, stood in for Kardashian's NBA player beau, donning stilts to accurately reflect Humphries' 6-foot-9 frame.

Kardashian and Humphries weren't the only well-known celebs Ripa, 41, portrayed Monday. She also suited up as Kate Middleton, Jersey Shore's Sammi "Sweetheart" Giancola, Lacey Schwimmer from Dancing With the Stars and Katy Perry.

Ripa's morning counterpart, Regis Philbin, missed this year's Halloween fete, but a stand-in joined Ripa in his place: Heidi Klum!

"It's very hard" being Philbin, Klum said. "All these wrinkles. I can only deal with it for so long."
