EASTENDERS fans know her as downtrodden brunette Little Mo Slater throughout the early 2000s.
But Kacey Ainsworth has appeared as a wavy-haired blonde telling followers: “This is my natural hair.”
The star – also famous for playing Cathy Keating in ITV’s Grantchester – posted pictures of her real hair on Instagram.
She told fans: “This is my natural hair. Just air dried. Been inspired by the #curlygirl stories on #insta to stop blow drying the bejesus outta my hair.
“Those who knew me in the 80s will have hazy memories of this style.. Haven’t had it cut in yonks and about to go to a friends bbq who has never seen the real me!”
Kacey added: “#curlyhair any advice welcomed #curlyhairdontcare well do a bit.”
Holby City’s Angela Lonsdale spoke only in emojis, adding: “.”
Kacey joined EastEnders as poor Little Mo along with the rest of the Slater sisters in 2000, twice winning Best Actress at the British Soap Awards.
She quickly found a place at the heart of the drama with her first husband Trevor, a violent, iron-wielding brute.
Her love life on the show was as haywire as any soap character, first hooking up with Trevor’s enemy Billy Mitchell after his death.
She then embarked on a relationship with brother-in-law Alfie Moon.
Kacey has also appeared in Grantchester, Casualty and The Worst Witch.
