but we don't have to wonder any more, as she took to Instagram to give us the lowdown!
On Wednesday (30 November), Lillie listened to her make-up-obsessed fans and followers (us included - duh!) and gave everyone a breakdown of the beauty buys she swears by for that everyday glam.
"I'm definitely not a beauty expert!!," Lillie captioned a stunning selfie before going on to write, "But [this is] the make up that works for me and is my go to day to day. Also the products I used here..."
Alongside celebrity make-up artist approved favourites such as the NARS Creamy Concealer and Giorgio Armani's world famous Luminous Silk Foundation (Kim Kardashian is a fan, dontcha know), Lillie revealed that her beauty bag just wouldn't be complete without one affordable, high-street buy in particular - and we reckon it makes her entire look.
The product in question? Soap and Glory's Love At First Blush, £11, of course! She loves the Pink, Pop, Pearl shade.
After defining her cheekbones with her favourite Chanel bronzer, Lillie reaches for the much more purse-friendly buy and with a blusher brush, swirls the shimmer-flecked pigment all over her cheeks and up towards her temples.
If you want an insane glow a la Lil, dust a little down the centre of your nose and along your Cupid's bow using a fan brush.
"Love this post, thanks Lillie!" wrote one of her Insta-followers, while another said, "Highlight on point girl!"
Lillie isn't the only reality star to sing her love for the feature flaunting highlighter though, as Love Island's Sophie Gradon recently revealed that she can't imagine her make-up bag without it, either.
Guess we'll see you in the queue, people...
