The 47-year-old singer - who has sons Kingston, 10, Zuma, eight, and two-year-old Apollo with ex-husband Gavin Rossdale - has recently returned to live performing and admitted she took a lengthy break from the stage because it is so demanding. She said: ‘’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.–CM
