Lily Allen feels like she has an "alien" inside her.

The LDN hitmaker is currently expecting her second child with husband Sam Cooper and is finding carrying the baby a peculiar sensation.

She tweeted: "Alien, inside me. #weird (sic)"

On 25 November Lily and Sam celebrated the first birthday of their daughter, Ethel Mary, and the 27-year-old pop star has also been reminiscing about the "excruciating pain" of her labour, but admitted motherhood was worth all the agony.

She tweeted on Ethel's birthday: "This time a year ago I was in excruciating pain. It was worth it. #1 #burtday (sic)"

Last week, the Not Fair singer fainted while Christmas shopping in London department store Harrods.

Fortunately, Lily was fine and decided to tuck into a croque monsieur - a toasted cheese and ham sandwich - to give her some much-needed energy.

She tweeted: "Just fainted in Harrods. #croquemonsieur needed."

And she recently bit the inside of her cheek during a recent meal out and was in a lot of pain for hours afterwards.

She tweeted: Went for dinner with pals @sebchew and @msaimeephillips and bit off the inside of my cheek. #f**kingpainful (sic)"
