The pop star and mum-of-two was spotted out in London yesterday (4 February) at The Ultimate Pub Quiz charity event, which was held in support of youth homelessness charity Centrepoint, and flaunted her fab post-pregnancy figure in a gorgeous black pencil skirt with white panels down the side and a plunging black top.
She finished off her smart and chic ensemble with a pair of quirky black and white patterned heels and kept her jewellery to a minimum, simply opting for a cute, long necklace.
Lily also added her own twist to the all-black look by sporting bright pink acrylics on her nails.
She was joined at the pub quiz by the likes of Jonathan Ross, Sara Cox and Scott Mills and it sounds like the group had an eventful evening, as Lily woke up this morning and confessed that she was "a bit hungover" and craving pizza.
One person that wasn't present at the charity bash last night was former star of The Apprentice and straight-talking TV personality, Katie Hopkins, who recently blasted Lily for gaining weight during her pregnancy.
During an online interview, Katie was heard slating the chart-topping pop singer for being "boring" and "looking pretty hideous", as well as claiming that she'd gained "two stone" from having a baby and was only famous because of her father, actor Keith Allen.
Lily was quick to hit back though, and opened up about her body shape on Twitter yesterday, explaining that she had put on weight during her pregnancy and comfort ate because she was terrified of losing her baby after previously experiencing a still birth.
The songstress - who is mother to daughters Marnie Rose and Ethel Mary - then deleted her tweets, but later posted a photo of her looking trim in a sexy black minidress.
She captioned the photo: "Just going to the shop , want anything Katie?"
