BBUK kicked off its fourteenth series yesterday, as the first nine Big Brother 2013 housemates were revealed.
But in a twist, one of them was a mole, with 'Postman' Michael really an actor who is under complete control from both Big Brother and us viewers.
He can't win the show, but the £100,000 prize is very much up for grabs for the remaining eight.
Bookies William Hill is already offering odds of 7/2 on 23-year-old Sam, who told in his VT last night how he's told he looks like Harry Styles.
We still don't see it!
Sophie Lawrence is favoured at 8/1, and twins Jack and Joe - who are counted as one housemate - are at 9/1.
Self-confessed gold digger Jemima Slade is very much the outsider at 33/1.
"There are fewer housemates this year than there have been in the past and Sam is the clear favourite of the few that are in there," a spokesperson said.
Big Brother UK continues with its Part 2 of its live launch tonight on Channel 5.
