With a new line of clothing in the works, British singer (and sassy bride-to-be) Lily Allen is adding designer to her jam-packed resume.

The 25-year-old pop star is joining forces with her sister, Sarah Owen, and getting into the fashion game with a new collection focusing on vintage-inspired garments, according to a report this week in Women's Wear Daily.

The line will be called Lucy in Disguise, which is also the name of the sisters' vintage shop located in London's Covent Garden district. The new collection was reportedly designed with a fictional clotheshorse, named Lucy, in mind.

"(Lucy's) a time-traveling fashionista, who's inviting you to explore her wardrobe," Allen explained at a press conference. "It's a great opportunity to play with the character."
