The girl group member decided to give her locks a break from the various weaves, wigs and hair extensions that she often sports and showed her fans what her hair really looks like in a candid snap uploaded to Twitter.
Flaunting a head of enviable curls, Leigh-Anne looked fresh faced and super sweet in the picture and encouraged her followers to go au naturel too.
She wrote the caption: "Its an all natural one today! #nomakeup #naturalhair embrace it! X"
Leigh-Anne, 21, also favoured a make-up free face for the morning (16 September) and we have to admit that we're pretty jealous of how flawless her skin still is - even without a scrap of concealer!
We'd love to know what her skincare secrets are.
Little Mix are back in the UK now after a whirlwind trip to Japan, where they went to pay a visit to their Japanese supporters.
The four girls - including Jesy Nelson, Perrie Edwards and Jade Thirlwall - were seen landing at a Japanese airport last week in various eye-catching outfits, as they greeted their international mixers.
Perrie also flashed her new engagement ring, after debuting the rock at fiancé Zayn Malik's film premiere with One Direction last month.
