I never knew I could be this happy: Jimmy Fallon

Los Angeles: Funnyman Jimmy Fallon has revealed that after becoming a father last July sleep has become a pretty scarce commodity. Fallon, 39, brought home daughter Winnie Rose, delivered via surrogate, last summer, after he and his wife Nancy Fallon struggled with infertility for five years, reportedly. "When you have a baby, sleep is not an option. You can`t sleep. Even on vacation, you wake up at 6:30 am. But being a father is the most exciting, amazing thing that ever happened to me. And everything`s going well on the show. My life has never been this cool," he said. And as he gets ready to celebrate his first Father`s Day, Fallon said he is happier than ever. "I didn`t think it was going to be this fun. But everything just gets heightened when you have a baby. The volume gets turned up on life. I never knew I could be this happy, and that`s the truth."
