The Celtic Tiger may be dead and gone -- but nobody told Jedward.
John and Edward Grimes -- decked out in tiger-print tailed jackets, black leggings and trainers with pandas' heads on -- cartwheeled down the runway into the Big Brother house.
The fast-talking pair, who found fame on the 2009 series of The X Factor and went on to represent Ireland in this year's Eurovision, were the last housemates to enter.
The high-octane pair have been installed as favourites with the bookies, alongside glamour model Amy Childs.
They joined celebrities including Kerry Katona, American Pie actress Tara Reid, Paddy Doherty of Channel 4's My Big Fat Gypsy Wedding and David Hasselhoff's ex-wife Pamela Bach. Once the line-up was complete, Big Brother ordered one housemate to the diary room.
Katona volunteered and was given a secret mission to be chosen as the house's biggest diva in a vote today -- or face punishment.
"I'm not a diva. Why couldn't I let someone else come in?" she said.
In the coming days, 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.
Channel 4 axed Big Brother last year and the new show -- hosted by Kildare native Brian Dowling -- is being shown on Channel 5.
