The Cilla actress was spotted heading to private members' haunt Groucho Club in Soho, turning heads while flaunting her latest striking makeover.
The starlet is no stranger to a bold hair colour - back in May, Sheridan dyed her barnet a super-bright sky blue shade, just a few weeks after showcasing a bubblegum pink 'do.
She then rocked a long golden blonde bonce, but has since gone back to her trend-setting ways with another unusual hue.
Sauntering down the pavement, Sheridan rocked a silver pixie crop which boasted a hint of lavender, which she had dyed just a few hours before.
Taking to Twitter earlier that day, Sheridan wrote: "New hair & nails coz....Why not?! Merry Xmas u beauties! hope you have the best one yet! love u all long time!"
Opting for a rock chick vibe for her evening outing, the actress sported a leather biker jacket teamed with faded blue-wash jeans, plus a pair of black wedge boots.
And judging by the smile on her face, she seemed pretty chuffed with her brand new look!
