And the 'Hello' singer did again on Tuesday (22 December) by teasing us with a simple, classic colour on the top of her nails... but with all manner of sparkle going on at the back. Whoop!
Adele's recent return to music has totally propelled her to the top of our style radar again, and after revealing a fabulous new choppy haircut last week, we know her name is going to be on every hairdresser's lips way into 2016 and beyond...
And thanks to top celebrity manicurist, Jenny Longworth – who's been caring for Adele's digits for a while now – she's set to maintain nail icon status at the same time.
Kind of showing off a bit, right?...
We spied Adele's latest mani on Jenny's Instagram feed on Tuesday and while we love the rich, dark green polish Jenny's used on her super-long tips, the gold, glitter hiding underneath is what's really special about this look.
The even better news is you can add a touch of sparkle to any nail colour – as long as your tips are long enough, of course! And by that we mean really, REALLY long, otherwise you'll end up with glittery fingertips if you don't have enough nail to paint.
Never a good look.
To try it at home, we love Nails Inc Snow Globe Nail Polish in New Globe Walk, £15, boots.com which is a gorgeous gold shade and looks fabulous with classic red, black, navy or deep green nails like Adele's.
You could also try a silver glitter like No7 Nail Effects in Starry Sky, £7, boots.com – perfect with solid purple, deep grey or baby pink nails.
