The Jonas Brothers' reunion was almost spoiled by Kevin's 5-year-old daughter, Alena.
The bros revealed the story on The Tonight Show with Jimmy Fallon on Wednesday. Can you believe the reunion was a secret for a year?
Kevin said, "[Alena] did tell her entire school that the Jonas Brothers were coming back -- before the Jonas Brothers were [officially coming back]."
Kevin continued saying, "Luckily, those 5-year-olds [were] tight-lipped."
