Somewhere Only We Know singer Lily Allen decided to make her music comeback because she got "bored" staying at home.

The 28-year-old star, - who has two young daughters, Ethel (2) and Marnie (14 months), with husband Sam Cooper - retired from music in 2009 but made a comeback late last year and admits she did so because she felt unfulfilled spending her days at home.

Speaking to France's NRJ Radio, Lily said: "Why did I choose to come back? I ran out of money! No, I'm joking! I thought I'd be a really happy mum just sitting at home, playing with my kids, that was my dream.

"I love my children, but I'm a very impatient, busy person naturally so two babies, neither of them can talk, it was quite boring! Staying at home all day talking to people that can't talk back.

"I didn't realise how much of a creative person I am and that I need somewhere to put my creativity."

Lily further explained that motherhood has made her think differently about songwriting, adding: "When I write music now I'm conscious that I have two children and they're going to hear it. I can't be too sexy or gross or rude because that would be embarrassing for them. It's a different kind of me, but there are still the same elements."
