A professional actor, posing as a postman from Co Cork, has joined the Big Brother House on Channel 5 as part of this year's Secrets & Lies theme.
Twenty-nine-year-old Michael Dylan from Cork has been recruited by the programme makers to "spin a web of secrets and lies" in the house by pretending to be a contestant.
In a video, he told viewers: "I've been recruited by Big Brother to work for you."
He added: "You control me. You want to know what the secret is? You're looking at it."
