Big Brother wasted no time in getting mean last night by telling Kerry Katona she had to act like a diva for a secret task.

Once all the housemates had made their grand entrances, Big Brother ordered one of them to the diary room.
 
Katona volunteered and was given a secret mission to be chosen as the house's biggest diva.

Big Brother told her she had to throw a tantrum before returning to the diary room for further instructions.

Katona was told housemates would tomorrow vote on who was the biggest diva and if she was not chosen, a punishment would be given.

"I'm not a diva. Why couldn't I let someone else come in?" she said.

William Hill tonight installed Childs and Jedward as the joint favourites to win with odds of 3/1. Laviscount is just behind on 9/2.

The bookmaker gave the longest odds of 25/1 to Lyons.

Last night's show from the house in Elstree, Hertfordshire, ended weeks of speculation about the line-up.

Viewers can expect to see sparks fly, friendships form and various humiliations for the stars who have agreed to take part for fees which will total hundreds of thousands of pounds.

Many will also be keeping a keen eye on the fortunes of the programme itself, to see how it will fare in the ratings following its switch from Channel 4 to 5.

Other shows which have moved to the station from various networks - including Neighbours and Home And Away - have seen a near instant drop in viewers.

Channel 4 axed Big Brother last year after 11 series of the main show and a number of celebrity versions.

It was a key priority for media tycoon Desmond when he acquired Channel 5 last year, although the deal to secure the programme took many months.

As soon as the celeb series is over, the regular Big Brother begins. Members of the public who have made it through the audition process will enter the property for several weeks until a winner is crowned.
