Jimmy Fallon's life has never been better.

The 39-year-old presenter is enjoying fronting 'The Tonight Show' - which he took over in February - and says being a father to Winnie Rose, who was born via a surrogate last July, is the most ''amazing'' thing he has ever done.

He said: ''This has been the craziest year of my life. 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.''

Jimmy admits he never expected to enjoy parenthood as much as he has been.

He added: ''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.''

However, Jimmy admits he and wife Nancy have been left longing for a lie in since having their daughter.

He added in an interview with People magazine: ''When you have a baby, sleep is not an option. You can't sleep. Even on vacation, you wake up at 6:30 a.m.''
