Lily Allen has apparently tweeted lyrics from her new single.

The pregnant singer has come out of retirement to work on fresh material. Lily took to her Twitter account to voice her views on parenting on Tuesday, and later claimed the posts will appear in her new song.

“Sometimes there are lovely Dads who take their responsibilities very seriously and work very hard to look after their babies these men should be applauded,” she wrote. “BUT, sometimes, quite often, when the baby’s cry a lot the man gets frustrated and leaves the baby and the lady that had the baby. He sticks his fingers in his ears and pretends that the baby isn’t really there, he stops answering his phone when the lady calls.

"The lady gets very sad and feels very alone and angry and even though she loves her baby more than anything ............She wonders what her life might have been like if she had never had the baby in the first place (sic).”

Lily then followed up her tweet with a message that sparked a frenzy among her fans.

“thosemwere the lyrics from the first single , EXCITED ? (sic)” she teased.

The 27-year-old star has daughter Ethel Mary – who will turn one on November 25 – with her husband Sam Cooper and she is looking forward to welcoming another child soon.

Although Lily loves being a mother, she admits it can be difficult to juggle her demanding career with raising a family.

“ok, Babies are lovely but quite hard work,” she tweeted on Tuesday morning. “Its really hard to work and have a baby at the same time, because a baby cant stay at home on its own all day while you go to work (sic).”
