Martine McCutcheon urged her followers to take their time as she shared a pic on Instagram - in which she looked unrecognisable.
The ex-EastEnders actress, 45, shot to fame playing Tiffany Mitchell in the BBC soap, but there was little sign of Tiff in the glamorous photo.
Dressed in all black, with her hair pulled back off her face, sporting shades and a YSL bag, Martine looked trimmer than ever, telling fans: "She’s off “out out” for a walk folks!
"I know it doesn’t sound like anything brilliant - But I’ve had one of those days where it’s taken me FOREVER to get myself out of the door today!
"Jack's pacing about like a mad man as he did the school run this morning and he’s losing the will to live! Even the dogs are rolling their eyes at me But sometimes I just have so much to do and think of things that no one else would in the family!
"Right - I’m off! Note for the day: Do things at your own pace, in your own time…
"The world can wait #truetho #monday #couldntgetoutthedoor #ahwell #whatever PS. Brilliant how shades make an outfit… never ceases to amaze me."
The actress' post was met with a flurry of support from her fans with several commenting the mum-of-one on how good she looked.
One said: "Absolutely beautiful inside and out. You look amazing, super healthy and pretty."
While another gushed: "You look incredible".
Martine married singer Jack McManus in 2012 and the couple share a son, Rafferty Jack, who was born in 2015.
The Perfect Moment singer has just launched a modelling career after being signed by the prestigious Elite model agency, which represented fashion icons Cindy Crawford and Naomi Campbell.
Speaking about the secret to her stunning physique, Martine told Sunday magazine: " It’s taken me such a long time to look through all the stuff that’s out there, and just do what works for me.
"So it’s not as simple as just going on a crazy diet. I just feel like it’s really important to encourage women to just be the best version of themselves.
"The 80/20 rule is what works for me."
In a nutshell the 80/20 rule encourages healthy eating for 80% of the time, with more freedom for the other 20%.
Martine explained: "For 80% of my week, I will have mainly just healthy proteins, vegetables and fruit, organic and veggie juices, and Flora ProActiv spread.
"And then I’ll have treats 20% of the time – I’ll have that slice of pizza, chocolate or a G&T to celebrate a friend’s birthday.
"I’ll do it because I know that for most of the week, I’ve been doing the good bits for my heart."
