“I was 16 or 17 and took two weeks off school to shoot two episodes,” she shared in the video posted to TikTok, which featured footage from the appearances.

At the end of the clip, a teenage Ratajkowski comes into the frame and interacts with the characters Gibby, played by Noah Munck, and Sam, who was portrayed by Jennette McCurdy.

“Gibby, my first love lol,” the star then wrote, also noting, “I met Jennette McCurdy and her mom.”
