The new series centres around Gemma and Simon's divorce.
The story is picked up two years from the end of series one and relationships don't seem to have healed, while actress Suranne has described the characters as "damaged people".
The scenes on the first day of filming showed Gemma leaving a nightclub a little worse for wear.
She was spotted and photographed by her estranged husband who may use the pictures as evidence in their messy divorce.
Meanwhile a teaser clip has shown Gemma and Simon's teenage son Tom carrying a knife.
Suranne has revealed that after the first episode of the new series, the show will "shift" and take a "dark" turn, saying: “Gemma doesn’t behave well, and before she did that through hurt and now she’s channelling her anger [differently].
"It becomes dark and twisted, so she doesn’t believe in redemption for [husband Simon] but that’s the beauty of our story.”
