“The bad news has been really difficult for them to take and they are absolutely heartbroken.
“Lily’s entire outlook on life changed after she found out she was pregnant. She was looking forward to being a mum and starting a family with Ed.
“She had turned her back on her party girl image and had turned over a new leaf.
“They are surrounded by friends and family are offering support. It is a really difficult time for them.”The singer recently told how her pregnancy was a huge surprise.
She said: “I’ve looked forward to being stable my whole life. My parents are amazing, but it has been a whirlwind upbringing.
“I have got my eye on the prize, which is having kids and getting married and cooking dinner and doing homework with my children.”
Her spokesman said: “We can confirm that Lily Allen has suffered a miscarriage. She and her partner Ed Simons will be making no further comment and we ask that their privacy be respected during this difficult time.”
