Lily's Heart Scare Loss

Lily Allen has revealed she lost weight because doctors discovered she had a heart murmur.

The 22-year-old sparked concern when she shed 19lbs and dropped from a size 12 to an eight in just six weeks.

But the Smile star said the weight came off when she was told the "scary" news that she had the heart condition.

She told Grazia magazine: "I found out I had a heart murmur about three months ago."

"I had switched doctors and just went for a routine check up, which is when they discovered I had this irregular murmur."

"I have been asthmatic all my life, but this was really quite scary. When they asked me how much exercise I did, I had to be honest and say hardly any."

She said: "I make sure I work out three times a week now, and I don't hold back."

"It's a hardcore routine and I'm usually in the gym for at least an hour-and-a-half."

"I used to love nothing more than sitting in front of the telly with two packets of Ginger Nuts and two bags of milk bottle sweets - and I'd devour the lot."

"But this heart thing has made me cut back on all that kind of c**p."
