Christina Aguilera has given up junk food - because she is paranoid she will have a heart attack.
The "Dirrty" singer is a self-confessed junk food addict, but insists she only eats it very rarely because she is too worried about the health implications of munching on it.
She told Britain's TV Hits magazine, "I am a junk food lover, but I've had to curb that quite a bit since I'm not a teenager any more. I think it's important to take care of yourself, especially as a woman. Mostly I think it's really about curbing that so you don't get heart disease or cancer or anything like that."
Christina, who is married to music executive Jordan Bratman, puts herself through a grueling exercise regime and sticks to a reasonably strict diet to make sure she doesn't get fat.
She added, "I'm just trying to take care of myself, trying to get as much rest as possible, exercising every day and being healthy and getting my beauty sleep. I do a lot of weight training and some cardio - I like feeling strong."
