But she was back on the red carpet on Monday night (23 November) – and check out her new hair colour. Yesss, we've missed you Lily!
Lily has pretty much rocked every single hair colour there is over the last few years. And she's even gone so far as to wear them all at once, when she dyed her blonde bob a mixture of rainbow brights in the spring.
She then went back to blonde, before hitting the pink stuff in September and going almost fluoro for the rest of the summer!
Well, now there's a new colour in Lily town and it's a rich, purpley blue shade that we are in love, love, LOVE with.
Lily debuted her new do at the British Fashion Awards on Monday which were held at the London Coliseum and saw everyone from David and Victoria Beckham to Alexa Chung, Cheryl Fernandez-Versini and Rita Ora looking as gorgeous as ever on the red carpet.
Some of the hottest fashion trends of the night included sheer florals, black trouser-suits and lots of bare backs, but the Air Balloon singer chose a long-sleeved black dress with metallic floral detailing which also hit the spot perfectly.
And Lily's new hair was the perfect finishing touch to her cool look, which she wore parted to one side and accessorized with an embellised silver hairslide.
Who new blue hair could look so sexy? We think the key is that it's a dark, almost violet shade of blue which adds that touch of sophistication and still leaves Lily's sleek bob with plenty of shine.
