Jo, who played Tanya Branning in the BBC1 soap. was pictured earlier today (30 April) as she arrived at the This Morning studios.
The actress was due to appear on the show to talk about her new comedy series, Trying Again, and attempted to keep a low profile in dark glasses as she stepped out of the car.
But even with specs shielding her peepers and brown hair, we still clocked!
Last week, Jo revealed that she had dyed her hair brunette for a new TV role - and as an act of teenage rebellion!
Appearing on Lorraine, she said: "I've had a little makeover! I've been a bit teenage actually, I'm getting to play with my hair for once.
"It's like when I used to have temporary dyes as a teenage and would work through every colour!"
Trying Again premiered on Sky Living last week and it is based on the lives of Meg and Matt, who are attempting to rebuild their relationship following an affair.
