And her admiration was reciprocated when designer Karl Lagerfeld personally chose the singer for a new Chanel handbag campaign.
But despite their highly-publicised relationship, the 24-year-old's appearance at the brand's Paris Fashion Week show still managed to surprise guests.
Rather than joining fellow famous faces including Claudia Schiffer, Prince, who was joined by a beautiful brunette, and front-row regular Rihanna at the fashion event, Lily performed her latest single during the finale – uniquely making her entrance from beneath a hay bale.
In keeping with the farmyard-theme of the surroundings – before the show Karl described his inspiration as 'back to nature', citing Marie Antoinette in her shepherdess stage - Lily and her band were raised on a platform hidden beneath the forage.
Clad, of course, from head to toe in Chanel, the star sang her hit, It's Not Fair, to the star-studded audience as models strutted by.
While the show itself was certainly theatrical, Germany-born Karl was keen to emphasise there are no costumes in his vision for the next season.
White lace blouses, puffed sleeves, crocheted dresses, full skirted frocks and clogs – set to be big next season - all made their way down the runway.
It wasn't all rustic simplicity, though. While many of the models held baskets of flowers, others produced thoroughly modern Blackberries from quilted purses.
"This is Coco Country", said the man himself. "It's not peasant girl, it is girl visiting the country."
