VIDEO : The Key Ingredient Adele Was Missing When She Wrote '25'

In the past, Adele 's incredible albums have been a reflection of where she is in her life?typically a little sad and heartbroken?but something's different with 25 , and it's not just her age. Sitting down with Matt Lauer on the TODAY Show Monday, the Grammy Award-winning singer admits the birth of her son completely changed her life, including her music and writing. After releasing her sophomore album 21 a few years ago, she described her life as "uncertain" to Lauer. But now? She's happier and healthier than ever before. In fact, that sort of happiness actually made it incredibly difficult to write 25--she didn't know what to write about, because she wasn't sad!
