She's supposed to be tucked away in the studio mastering her hugely anticipated second album.
But not last night. The Smile singer partied until the early hours yet again, this time in Punk, Soho, with her best friend T4 presenter Miquita Oliver, her little brother Alfie Allen, and his new girlfriend actress Jaime Winstone.
She again emerged from the club looking rather worse for wear, struggling to maintain her balance.
It's been a week of back to back partying for the singer.
On Monday, she had to be carried from a car into the home of her new party companion Camilla Fayed.
After partying at London's Shoreditch House for the launch of Fashion House Chloe's summer 2008 collection, unable or unwilling to walk, she was carried to the door and then helped inside by her companions.
Still, proving her wild child credentials are still in tact, the pop star continued partying until after 4.30am.
Perhaps Lily week of none stop partying is in celebration of her own TV show, which is set to debut on BBC Three in 2008.
The still untitled show will feature an audience comprised entirely of guests selected from her MySpace 'friends' list, with audience members getting the opportunity to present parts of the show.
She is also rumoured to be considering another TV role, this time as an assistant on the hit show Dr Who.
