Former Coronation Street actor Sean shared the snap with fans on Monday as the cast took a break from filming.
He captioned the snap: "Squad".
Michelle shared a similar photo with fans last week saying the cast - including Ben Aldridge (remember Captain James' epic "ditto" quote?) - had gathered for a read-through.
Cast and crew have flown out to Kenya for the second series of the BBC One drama, which is fictionally set in South Africa.
Fans of Our Girl will know that Sean starred in the very first series in 2014 as Fingers, but Michelle is a new recruit to the show.
Former Corrie actress Michelle joins the second series as the lead character, Corporal Georgie Lane, taking over from EastEnders star Lacey Turner, who played Molly Dawes.
New pictures were released of Michelle last week in character as Georgie.
She said of her new role: "First time I put on the uniform it felt quite surreal but then I immediately felt the sense of duty - as if I was in the military."
Our Girl first aired on BBC One as a one-off special in March 2013. It then returned in September 2014 as a five-episode series.
