Ryan Thomas shared a sweet clip of his son Roman and his daughter Scarlett on the set of Waterloo Road after Scarlett landed a role on the show.
The actor, 38, shares Scarlett, 13, with ex Tina O'Brien, and Roman, two, with his wife Lucy Mecklenburgh.
He took to his Instagram Stories to share a black-and-white video of Roman happily hitching a ride on Scarlett's back as she walked through the set's hallway.
"Little bro picking big sis up from work @scarlettjthomas26," he captioned the post and added a few heart emojis.
Little Roman took in the views of the set as he wrapped his arms around his big sister's neck.
The adorable tot got to have a personal tour of the set after Scarlett landed a role on Waterloo Road in February.
Scarlett landed a role on the BBC show's reboot, where she will be playing the daughter of her famous uncle Adam Thomas, who plays Donte Charles on the series.
Adam made the exciting announcement that Scarlett will play his on-screen daughter Izzy during an appearance on BBC's Morning Live. He said in February this year: "I can't believe I'm actually saying this, I feel like I'm working for Marvel, but what I can tell you is that my little niece Scarlett Thomas is going to be joining the cast of Waterloo Road.
"She's playing my daughter on it. If you're a fan of the show, Donte and Chlo had a kid and she's now grown up. My brother's daughter gets to play my on-screen daughter."
Roman and Scarlett recently gained another sibling after Lucy gave birth to daughter Lilah in June.
She explained how being a mum of two can be 'absolute carnage'.
In a recent chat with Mirror, Lucy opened up about her growing family: "I was talking to Ryan about this, I was saying it's beautiful chaos."
"I love it, there are so many gorgeous moments I just want to bottle up, when they're cuddling and kissing and you're all chilled, watching a movie together but then there's absolute carnage as you can imagine," she added.
"Toys flying everywhere, I'm having to guard Lilah from getting a dinosaur in her face. "
Lucy had Roman in March 2020, days before the world went into lockdown in the coronavirus pandemic.
She credits her fiancé, former Coronation Street star Ryan with helping her through and says this time around it's been easier.

"I actually found the transition from one to two easier than nought to one," she said
Lucy is also a stepmother to Scarlett.
Ryan and Scarlett's mum, Tina, dated for six years after meeting on the set of Corrie, but are said to hardly speak anymore.
Tina gave birth to daughter Scarlett Jacqueline Thomas in October 2008, and months later her relationship with Ryan hit the rocks.
The couple's split was said to be anything but amicable with Tina previously claiming that Ryan broke up with her just a week before their daughter Scarlett's first birthday because she 'just didn't do it for him anymore.'
Despite their history, the couple continues to co-parent their daughter.
