Big Brother 2013 #WhatsTheSecret - it's mole Michael!

Big Brother 2013 Secrets

The Big Brother 2013 #WhatsTheSecret has finally been revealed, with a mole in the house!

This evening saw the first half of the launch show kick off on Channel 5, hosted by Emma Willis.

First in the house were twins Jack and Joe, followed by firebreathing glamour model Sallie Axl.

Self-confessed gold digger Jemima Slade was next, together with Postman Michael... or so we thought.

But in a VT shown only to us viewers, Michael confessed the truth.

"My name is really Michael, but everything else is a lie, I'm a professionally trained actor," he said. "I'm here to mess things up and to cause havoc for the housemates. I have been recruited by Big Brother to spin a web of secrets and lies, to toy with the housemates."

The 29-year-old is not a housemate at all, but instead will be controlled by both Big Brother and us viewers.

Throughout the series, we'll get the chance to set Michael various tasks and challenges, which will ultimately decide the course of the series in its early stages.

Emma teased that Big Brother will set Michael his first mission later tonight, and we can't wait to see what fireworks he begins to cause!

Big Brother 2013 continues live on Channel 5!
