But ahead of her big Our Girl debut tomorrow night, Michelle has shared a new behind-the-scenes picture - and that is exactly what it shows!
Taken on the first day of filming, 29-year-old Michelle can be seen in her combat clothes while enjoying a well-earned water break in between scenes.
The majority of the BBC One drama was filmed in South Africa and the actress has been reminiscing about her two months spent there earlier this year.
Alongside the photo, she tweeted: "Where it all began... 1st day filming in South Africa. The start of an amazing journey #georgielane #ourgirl."
Last night (5 September), Michelle cut a very different look as she attended the official preview of Our Girl in Manchester.
Following the screening, her husband Mark Wright was quick to sing his wife's praises, while telling fans how proud he is of her.
He tweeted: "Seriously though.... Look at this woman from tonight.... No words.... Can't tell you how proud I am of what she has achieved. OUR GIRL.... this Wednesday at 9pm on BBC. The first episode is sensational. Enjoy."
In the new series of Our Girl, Michelle has taken the helm as leading lady following Lacey Turner's departure. The former Coronation Street star is playing a new character, Corporal Georgie Lane.
