## Key points

- Grande fooled De Niro and Stiller with a childhood aquarium story.
- She confessed the fish-tank incident was made up.
- Stiller’s true Foreigner recording story was doubted.

## Summary

Ariana Grande convinced Robert De Niro and Ben Stiller that she had fallen into a giant fish tank as a child during a game on The Tonight Show Starring Jimmy Fallon. The playful exchange drew attention to the cast of Focker-in-Law and Grande’s first role in the Meet the Parents film series.

Grande said she had been four and had accidentally entered the aquarium tank while watching her brother Frankie scuba-dive; all three men eventually believed her, though Fallon was initially doubtful. She then admitted it was “the worst lie” and said she hated lying. Stiller offered a true story in return, claiming he was present when Foreigner recorded “I Want to Know What Love Is”, but the others did not believe him.
