According to The New York Post, the singer kept forgetting the words to some of the band’s greatest hits during their performance on Good Morning America last Friday.

 

A source told the paper: “Gwen kept forgetting lyrics to the band's older songs ‘Underneath It All’ and ‘It's My Life.’

 

“She kept asking the early-rising crowd for help, and they joined in.”

 

Stefani also told the Daily Record that parenthood had left her feeling exhausted, which didn’t help.

 

The frontwoman said: “We were only able to get together three days a week and, because I had the kids, there was only a limited amount of time.

 

“I was exhausted by the time I got there, so it was a struggle trying to weigh and balance everything out with the kids. But it was that fight that made the record so great.”
