The supermodel, who is mum to 10-year-old Presley and nine-year-old Kaia, had a cameo role in the Disney series during a special Fashion Week episode, where a poster of Cindy is brought to life by teen wizard Alex (played by Selena Gomez).
"At my kids' school I'm Presley and Kaia's mum - I did do Wizards Of Waverly Place and now all of a sudden all the kids knew who I was," she told Hollywood Life.
Cindy, who is married to entrepreneur Rande Gerber, teaches her kids to stay grounded by trying to set an example.
"They watch how I behave. I'm from the Midwest so they watch how I treat other people," she added.
