Cleary told ChuckTV that she will play the role of Laura in an upcoming episode.
"Laura is a flight attendant who works for Marco, Dolph Lundgren's character," she revealed. "She may be a little more than just a flight attendant, though!"
The supermodel also admitted that she had originally auditioned for a different part in the NBC comedy-drama.
"I actually read for a completely different role and they brought me back for the character of Laura instead," she explained. "I am a fan of the show but it's hard to keep up with Tivo with my crazy schedule so I definitely had to play catch-up before I went in to read for the role."
Chuck returns to NBC tonight at 8/7c.
