The Jonas Brothers smile up a storm while celebrating the launch of their new book, “Burning Up: On Tour with the Jonas Brothers” at the Sunset Tower Hotel in Los Angeles on Monday.
The musical trio — Nick, Joe and Kevin — performed their song “Shelf” on The Tonight Show with Jay Leno and sat down to talk with the host for a quick minute. Nick, the youngest of the trio at 16, explained the hilarity behind Kevin’s constant reminder about his birthday. He shared, “Here’s the thing. Kevin always makes a point to say, ‘You know, I hope you guys don’t forget it’s my birthday on this day because last year you forgot.”
Kevin goes on to explain that he does it on purpose. He said: “It was six o’clock on my 18th birthday when they finally realized that ‘Oh yea, it’s Kevin’s 18th birthday’.”
