Ronan Keating has admitted the decision to cast him in his first film was a "risk".
The singer, who is better known for fronting Boyzone, will star in the upcoming Goddess alongside Laura Michelle Kelly.
Speaking in Cannes, where the duo made an appearance to support the film directed by Mark Lamprell, Ronan said his debut role as an actor does not mean he will leave music behind.
"I'm finishing an album at the moment that will come out in August," he said.
"I hope I can do the two in tandem, I would like to think so. It just needs someone to believe in me again like Mark believed in me. It's a risk taking someone who's a musician and putting them into a film."
Goddess tells the story of young English mum Elspeth Dickens, played by Laura Michelle, who is stuck in a remote farmhouse in southern Australia with her twin toddlers while her marine scientist husband James, played by Ronan, is away studying whales.
Lonely and isolated, she installs a webcam over her kitchen sink and sings songs about domestic drudgery to the world wide web.When she becomes an internet sensation she has to choose between fame and family or risk losing it all.
The pair said they both had a lot of fun and definitely now had the "film bug".
Ronan, who is currently working as a judge on Australian X Factor, added: "It was a very different experience. I've made a load of music videos but dealing with dialogue and with other people, and reacting to them and things they say to you, it's a whole other minefield."
Laura Michelle said she was "really chuffed" when she heard she would be starring alongside the When You Say Nothing At All singer.
