London (ANI): Singer Alexandra Burke is watching her diet carefully because she is afraid of developing diabetes. The 21-year-old star's grandma was a diabetic and died from complications arising out of the disease and her mum Melissa suffered kidney failure due to the condition. But now Burke has vowed to manage her diet in a bid to keep diabetes at bay.

"My nan and my great-nan both had exactly the same thing. I have to be careful - I have to watch what I eat," the Daily Star quoted her, as saying.
