Scarlett, who plays Izzy Charles on the BBC One school series, has recently landed her first ever acting nomination for her work on the show.
Sharing the news on her Instagram account, the Sarah Barlow actress called the nomination a "proud mum" moment, writing: "So proud of @scarlettjthomas26, she's worked so hard on Waterloo Road and I've absolutely loved watching her portrayal of Izzy.
"Wonderful to see her talent recognised by @tvtimesmagazine as she's been nominated for an award."
Waterloo Road has been a springboard for the careers of many young British stars over the past few years, with Emily in Paris' Lucien Laviscount, Jenna Coleman and Bridgerton's Phoebe Dynevor all getting breakout roles on the show.
Waterloo Road will return for its 13th series on BBC One and BBC iPlayer.
