The singer - whose hits have included Naked - said: "The bikini shoots are getting harder, the older I get, but what I'm able to do now is relax and say to myself, 'This is me at 35, and after two kids. I may not be a supermodel, but I can just about get away with it'."
Louise, who has been married to her 37-year-old husband for 12 years, added: "I know there's a perception that Jamie and I have the perfect marriage, but we have our ups and downs. It worries me that if one day anything were to happen, it would hit us really hard, because we've got this image of perfection to live up to."
