Lily Allen kept fans up to date on her pregnancy as she posted a picture of her growing bump over Twitter.

The singer, who married husband Sam Cooper over the Summer, shared a picture of herself getting into the Halloween spirit.

Allen tweeted fans: ''Me, bump and pumpkin, i did it last night during x-factor.''

The London singer released her last album 'It's Not Me It's You' in 2008 and has no current plans to head back into the studio.

''I'm being taught how to knit. I'm so not rock 'n' roll any more. I'm embroidering too. I'm actually in the process of making cushions,'' Allen told The Sun.

"When I go to gigs and stuff, I get a slight pang of envy and I think, 'Oh I do miss being up on that stage'. But I have other priorities at the moment."
