HOLLYWOOD, Calif. — She hasn't dyed her hair blonde again, but Kim Kardashian has another new look.

The 29-year-old star recently slipped into a new face as part of her going undercover for the E! reality series Secret Celebrity.

"This was a real process," Kardashian writes on her blog. "I needed to get a molding of my face so I could have a prosthetic nose, cheeks, and neck put on!"

For her bit, Kardashian visited a special effects establishment notorious for making molds of Hollywood celebrities. She also took on the name Cynthia after her cousin Cici. And the end result?

"I look like a completely different person!" she says.

The episode with Kardashian, which also features Nick Lachey going undercover, airs Friday at 8:30 p.m.
