The former Coronation Street actress, 36, was spotted handing out flyers about a funeral during the scene while dressed in an oversized green khaki coat.
The star, who plays single mother Erin Croft, looked downcast while in character during filming.
Michelle donned blue tracksuit bottoms, a purple shirt and black boots.
In other snaps, the actress was spotted walking alongside her co-star Joanna Higson, who plays Sugar on the series.
Joanna’s character totted a bright purple fluffy coat, red checked trousers and bright red platform boots with a black soles.
The pair were filmed handing out leaflets, letting the characters know of another character’s surprise death.
Season six of the hit Sky comedy show will be released next year.
Michelle recently hinted that Erin will get into some sort of trouble with a petrol can – which she and Carol (Bronagh Gallagher) will use to top up an elderly couple’s car.
The series follows Vinnie O’Neill (Joseph Gilgun) and his five friends, including Michelle’s character Erin.
The comedy follows the group as they struggle to get by in the fictional town of Hawley, and often resort to petty crime for money.
When Dylan’s girlfriend Erin (Michelle) wants out to start afresh in a new town, Dylan (Damien Molony) is torn between following her or staying with the pals he thinks of as brothers.
The BAFTA-nominated series began back in 2019, as season four of the show was released last August on Sky Max and Now TV.
It comes after Brassic star Neil Ashton revealed he asked co-star Michelle to invite her husband Mark Wright on the comedy show.
In an interview with The Mirror, Neil said he’s going to ask Michelle about getting Mark involved with a cameo but fears he might be ‘too handsome’.
He said: ‘Michelle is one of the loveliest people. And Mark as well, they are so good together, those two. They have really lovely chemistry.
‘I’ve known Michelle a lot longer, so when you hear about someone you always hope they’re going to be nice. Has he ever had a cameo? I don’t know, I’ll message Michelle and ask her. He’s too handsome though – far too good looking.’
Michelle and Mark have been married since 2015.
Brassic is reportedly set ‘to be axed after the next series’ as the cast wish to moved on from the Sky comedy to work on other projects.
The show has just released its fifth season, with a special coming in December.
But a new report has revealed the show could be ‘unlikely’ to return after next year as the producers work on a sixth and final instalment.
A Sky insider told The Mirror: ‘Brassic is very unlikely to return after next year’s sixth series. It’s had incredible success, but the feeling among some of the cast is that it’s time to move on.
‘Ryan was considering leaving after series five, but was persuaded to continue by the bosses at Sky.
‘Michelle is also finding it harder to work her schedule around filming as she’s in demand for so many projects.’
A Sky spokesperson has denied that the show will end after series six, telling MailOnline: ‘Brassic has not been cancelled. The show remains one of Sky’s best-performing original comedies. With a highly successful series five launch just last week, it is a firm favourite with our customers.
‘A growing number of them continue to discover this award-winning series on demand and as it airs on Sky Max, Thursdays 10pm.’
