Showing off her maternity style overnight was Lily Allen. The popstrel, who is expecting her first child early next year, hit the red carpet at the premiere of Tamara Drewe in a '60s style maxi dress, which she accessorised with a sheep! Meanwhile, Lils is also busy gearing up for the launch of her fashion boutique, Lucy in Disguise, which is set to open on September 16th in Covent Garden. The official store launch follows a pop-up store in Selfridges which opened on Friday.

Perhaps the most exciting aspect of the store are the vintage pieces that Allen has worn during her performances, which will be available to hire or buy from the store.

According to Allen's publicist, Liz Matthews, Lily and her sister/business partner Sarah Owen have also designed a ready-to-wear collection, which is due to launch in spring 2011.

As for the store, well it has a "modern-day Biba," feel to it says Matthews. There will also be designated sections for different eras, for example the Twenties and the Fifties. And areas for a Bumble & Bumble hair salon, a Grey Goose vodka bar and a Playstation den.

Um... awesome!
