Mother-of-two Lily went to London venue Hotel Edition with her husband Sam Cooper and was having so much fun that she didn't emerge until the small hours.
Lily toted a bright blue bag, and her hair was also streaked with blue. Nice matching skills!
Earlier that night, Lily had been performing with DJ Mark Ronson and her ex-boyfriend Seb Chew in a pod in the London Eye. As you do!
Lil was loving it and inundated her Instagram feed with pictures from the Revolutions in Sound gig, which was live-streamed to music fans online and at the base of the Eye who got their silent disco on.
The 28-year-old said: "God I love my town."
Lily's been busy promoting her new single 'Hard Out Here', and after the gravity-defying gig she and her husband headed to a hotel to carry on the party.
We wonder if she was feeling a little jaded this morning!
