The pop star spent time in an Austrian recovery centre last November to be treated for stress and exhaustion and insists it is a myth that you be content in your life if you have fame and riches.
She said: "I had mental exhaustion but came back with a different outlook on who I was. It wasn't bloody rehab! People think, but you've got money, so you should be happy. I used to think the same, but money isn't everything."
Amelle also revealed she and bandmate Heidi Range support each other when they are dieting and help one another learn to love their imperfections.
The 'Get Sexy' singer added in an interview with Company magazine: "Heidi's always on a diet and works out all the time - she almost has to, bless her heart. I never understood that before. When I ballooned, I was like, 'Heidi mate, I'm so sorry about complaining about how skinny I was!' But everyone has lumps and bumps. I've got cellulite, who cares."
