New mum Sophie Rundle was back on the set of Gentleman Jack on Thursday, three months after welcoming her first child.  

And the 33-year-old actress' husband Matt Stokoe stopped by with their little boy midway through the day's filming, with Sophie doting on him while donning her blue period costume.

She is currently shooting the second series of the hit BBC period drama with on-screen lover Suranne Jones, who was also on set.

Sophie, who plays Ann Walker opposite Suranne's Anne Lister, was seen in a light blue gown, typical of the 1830s.

The floor-length number was tied at the waist with a black belt and featured heavy shoulder detailing. 

She added a pearl necklace, matching earrings, and wore her mane in curls.

The star sported a pale make-up tone with rouge on her cheeks. In later scenes, she added an elaborate hat with feather detailing.

Matt arrived looking casual, keeping a face mask over his mouth and nose, as per COVID-19 restrictions on set.

He wore a light blue shirt and navy shorts and a baseball cap, brandishing their child's baby seat.

He was seen handing their tot over to his mother, who is presumably still nursing him. Sophie could not stop smiling as she doted on her son and placed a white muslin over her shoulder.

Sophie also stars in Peaky Blinders - and was on set for the production just four weeks after welcoming her child.

She took to Instagram at the time to show herself juggling motherhood with her work as an actress.

Suranne seemed delighted to have Sophie back on set as her lover Ann. She posted a snap to Instagram of herself in character.

She penned alongside it: 'And we’re back! Diary✔️ watch ✔️ wife ✔️'

Suranne has been working on the upcoming series of Gentleman Jack since March. 

The actress, 42, joked that she was 'scaring people at work' and looked like a character from James Cameron's Avatar as she posted a pouty snap to her Instagram page when production first kicked off. 

Explaining her husband Laurence Akers had gifted her the beauty product - the Sub-Zero De-Puffing Energy Mask from 111 Skin - after she complained her face looked tired, the TV star headed off to work with the mask still on.

Quipping that her hectic work schedule involved 'months and months of filming', the mother-of-one captioned her funny snap: 'Gift from my husband after I complained my face looked tired for the millionth time!!

'Now I'm just scaring people when I arrive at work #avatar #monthsandmonthsoffilming #wheresmynormalfacegone. HAPPY FRIDAY.'

Suranne has been keeping busy by shooting scenes for the second series of her hit BBC One show in recent months.

The series is set in Yorkshire in 1834 and is based on the real life diaries of English landowner and diarist Lister.

The first series saw the couple torn apart when Ann was taken to Scotland, under threat of being married off by her brother-in-law.

But by the finale, the pair came back together when the philanthropist was called back to Yorkshire to visit her bedridden aunt.

Their reunion took place in a dramatic hilltop moment when Ann revealed she was finally ready to marry Anne.

Suranne often uses her platform to promote LGBT+ equality, so much so that the star was awarded The British LGBT Awards' Celebrity Ally prize during November's ceremony.
