Joking around with model Agyness Deyn, the girls were there to support their friend, Henry Holland, for his Fashion Week show at the Old Sorting Office in central London.
Agyness is best friends with Holland, whom she has known since childhood, and is the face of House of Holland.
Also joining Lily and Agyness were front-row regulars, Jaime Winstone and Pixie Geldof.
As well as doing the Fashion Week rounds, Lily has spent the past two weeks promoting her new vintage fashion venture, Lucy in Disguise.
What do you think of Lily's front-row style?
