How does one write a memoir when they’ve only been on the planet for 15 years? Well, some very famous celebs have lived more in their young lives that many will in a lifetime. Enter: The teen autobiography.

We asked Kathie Lee Gifford & Hoda Kotb their opinion on young stars writing autobiographies. Here’s what they said:

Kathie Lee Says: “It’s your personal story up to this point, but the truth is, at that stage of life, while you’re still making mistakes, you haven’t lived long enough to learn from them.”

Hoda Says: “It’s not OK. I vote that you wait until your brain fully develops.”
