The 47-year-old singe has recently returned to live performing and admitted she took a lengthy break from the stage because it is very demanding, reported Female First.
"Every time I go out on stage, I have to do my best. You can't just walk through it. You have to be in it, and its exhausting.
"I think it's one of the reasons I haven't toured solo in seven years, because the last one I did almost killed me, after having those two babies then going on tour and nursing an infant. Doing those No Doubt shows (in 2015) were super physical," Stefani said.
