The 'Air Balloon' singer had just performed at the Shepherd's Bush Empire, and headed to a warehouse party later that evening to continue her celebrations.
And while she donned towering heels onstage, Lily was quick to change into her ginormous chunky trainers afterwards!
The shoes in question are platform Buffalos and are part of the brand new Topshop collaboration with London-based designer Ashish Gupta, which launches in May.
Showcasing the perks of being famous, Lily was gifted her eye-popping footwear after attending the designer's catwalk show in February.
A few days later Lily gave her trainers their first official outing, sporting them while running down the Brit Awards' red carpet!
This time she teamed her look with loose blue-wash jeans plus a tummy-baring ruffled pink crop top, warding off the chills with a knitted hoodie.
We just hope she didn't twist her ankle, dancing in those bad boys 'til dawn!
