The 'Air Balloon' singer channelled one of her favourite TV shows on Monday (8 June), while she took to pampering her skin and deep cleansing her pores with a white, clay face pack...
"#whitewalker," Lily posted, along with this much-less-glam-than-normal selfie (above).
We're not convinced she really looks like one of the Games Of Thrones humanoid baddies (below) – she's thankfully lacking in the icy beard, hook nose and super-wrinkled skin – but hey, we love her reference to one of our fave shows of the moment!
Lily was struck down with an annoying smattering of spots along her jawline a few weeks ago which she also shared with her fans on Instagram.
We've all been there, right?
"How is it fair that I get acne at 30?" she posted with a snap of the offending area. "#1stworldproblems," she added.
The Brit star, who turned 30 at the beginning of May, generally shows off a pretty fabulous complexion, but proved in this selfie, that even she's not immune to the annoyances of the odd skin blemish. Big respect.
So, what's a girl to do to combat a little adult acne? Give your skin a deep cleanse with a clay face mask, that's what.
We can't be sure exactly which brand of face pack Lily is using in her most recent picture, but we know she's a big fan of Liz Earle and Clarins skincare products.
With that in mind, you could try Liz Earle Deep Cleansing Mask, £15.75, lizearle.com.
We also love Origins Out Of Trouble 10-Minute Mask, £23, origins.co.uk.
