Lily Allen pens 'powerful' song about losing baby in 2nd miscarriage

Lily Allen has written a "really sad, really powerful song" to describe her pain over losing her baby boy in second miscarriage in 2010 after a six month pregnancy.

The 'Hard Out Here' hit maker, who has two daughters with husband Sam Cooper, told Q magazine that she hopes the song makes the final cut, because it's a really important song to her, the Mirror reported.

Allen added that it's no use just singing about being famous or rhyming 'crazy' with 'baby' a million times over.
