Lily Allen has been discussing the motivation behind her pop comeback last year - boredom.

The 28-year-old singer told NRJ.com that she had missed the creative element of her work after quitting the music biz to have two children.

"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 had a hit with her cover of Keane's Somewhere Only We Know toward the end of last year.
