Lily ensured her midnight blue locks were the focal point of the look, setting off her heavy fringe and razor sharp cut with a dazzling hair clip.

The Not Fair hit-maker added a pair of pointy silver stilettos and a Chanel box bag to complete the ensemble.

She toned down her make-up, wearing 60s inspired winged eyeliner in a matching shade of electric blue, a nude lip and a matte complexion.

Lily was last seen sporting a choppy blonde bob after her pink 'do gradually faded out.

It's been months since Lily last sported dark locks, having previously experimented with purple, teal and rainbow hair.

The outspoken singer has been lying low of late, spending time with her young daughters Ethel and Marnie.

Meanwhile, Lily took to Twitter earlier this month after being accused of nepotism by another social networking user, triggering a rant about her actor father Keith Allen.

According to the Daily Mirror, the singer was involved in an exchange on the site, when she posted some lyrics to The Faces' song, Ooh La La, (I wish that I knew what I know now, when I was younger.')

One user replied: 'What, that you really are talentless and only "famous" off the back of Daddy... bore off!'

Lily reportedly hit back with: 'My dad walked out on me when I was 4, I'm sick of this. My dad was at Latitude when I headlined and didn't even come to see me.

'I've probably spent more time walking my dogs than I have with my dad my entire life. And I'm 30, too old to be running to anyone.'
