Lily Allen Talks Miscarriage, Eating Disorder In Channel 4 Documentary

It's been a hard year for Lily Allen, and now, the British singing star is revealing an intimate look at her struggles as they happened.

According to the Daily Mail, Allen featured in the Channel 4 documentary "Riches To Rags," which chronicled her life from last March to October.

Allen, who announced she was pregnant in August, suffered complications all throughout her summer and fall pregnancy, lost her child with now-fiance Sam Cooper at the end of October. It was her second miscarriage.

The star also talks about her struggle with an eating disorder that led to vomiting and other destructive habits.

"I used to vomit after meals. It's not something I'm proud of," she says in the documentary. "But, I tell you what, a lot of people came up to me telling me how great I looked and I'd be on the cover of every magazine... But I wasn't happy, I really wasn't... I would love to be the skinniest minniest person in the world but I can't do that without being unhappy - I like food."

Allen talked about finally being able to shrug off weight gain in an August cover story for Elle Magazine, in which she said she was okay with gaining weight.

"When I was on tour earlier in the year, I'd be on stage for one-and-a-half hours a night, so since the tour finished in March, I've put on about half a stone," she told the magazine. "But I do Pilates three times a week. I am still body conscious, but I'm not so concerned with it; I don't care as much."

That was a long road of hard work from her struggles in years past; in 2009, she revealed that she had body dysmorphic disorder, or a skewed body image that pictures imagined defects. That came two years after posting a desperate blog entry, in which she said she was in tears, considering liposuction.

"I used to pride myself on being strong minded and not being some stupid girl obsessed with the way I look. I felt like it didnt matter if I was a bit chubby cause, im not a model, I'm a singer. I'm afraid I am not strong and have fallen victim to the evil machine. I write to you in a sea of tears from my hotel bed in Seattle. I have spent the past hour researching gastric bypass surgery and laser liposuction."
