Cheryl is set to trace her roots in the new series of Who Do You Think You Are?
The former Girls Aloud star is seen in a sneak peek trailer for the upcoming season of the genealogy show, which sees celebrities tracing their family trees and uncovering secrets from their past.
The clip shows Cheryl walking past a river and looking at old photographs.
At one point she says: "I feel really really proud of him."
Cheryl is set to discover the story of her long and forgotten great grandfather - a Tommy in the First World War.
EastEnders actor Danny Dyer, Britain's Got Talent judge Amanda Holden, actor Sir Ian McKellen, Star Wars and Harry Potter actor Warwick Davis and presenter Liz Bonnin are also set to appear in the new series of the BBC show.
Tom McDonald, BBC head of natural history and specialist factual commissioning, said: "This year's series spans centuries of history and crosses continents to unearth extraordinary genealogical revelations for some of the UK's most beloved actors, performers and presenters."
