Big Brother Series Nine LogoBig Brother Series Nine LogoIt may only be two weeks away, but Big Brother betting fever is already upon us.

So is this the year of Big Brother's barmiest bets?

Clearly setting the tone for the ninth series, bookies Sky Bet are offering 10/1 for one of the female Housemates to enter the Big Brother house topless. Let's hope the weather holds out for them... 

Continuing the nude theme, it's only 3/1 for catching a stark naked Housemate in the pool during the first 24 hours.

Slightly more optimistically you can get 20/1 on two Housemates tying the knot this year and 33/1 for the first Big Brother baby! Surely Big Brother spawn is the last thing we need.  

Following Sam and Amanda's failure to secure a No. 1 single with Barbie Girl, Sky Bet are clearly playing it safe with 50/1 for a Housemate to score a Christmas No.1 by the end of 2008.  

Helen Jacob, Sky Bet's entertainment manager said, "With this year's series set to be bigger than ever, we're anticipating a Big Brother betting bonanza this summer. "

Whatever the outcome, it's clearly going to be happy days for the bookmakers with an estimated £15 million to be wagered on the show.

Bring on the Big Brother madness...
