"The great thing about this show is that you never know what’s going to turn up on the day," said Alesha. "I'm so happy to be reunited with Simon, Amanda and David, and to be surprised, shocked and amazed all over again at the talent on offer."'
Amanda echoed the former Mis-Teeq singer's statement, saying: "I can't wait to head off to the auditions. We always find some fantastic talent - as well as the bizarre and hilarious!
"I have a feeling that this year, as always, we will see some extraordinary things. That's what makes it so exciting. It will be brilliant to get back with all of the gang to catch-up, have some fun and I'm looking forward to getting into a lot of trouble with Alesha and making sure the boys are kept in order!"
Comedian David couldn't resist making a joke about Simon, saying: "I am delighted to be back on the panel with the three girls."
The music mogul himself retaliated by praising his fellow judges, except for David.
"Amanda is so much fun to work with and has great instincts," he said. "Alesha has proved to be a brilliant judge, has an amazing eye for talent and is a pleasure to be around. And, then there's David..."
From Monday the judges will set off around the country searching for this year's contestants.
Kicking off in Edinburgh at The Festival Theatre, Simon, Amanda, Alesha and David will then head to The Lowry in Manchester (29-31 January), The Hippodrome in Birmingham (5-7 February) and The Dominion Theatre in London (11-15 February).
Britain's Got Talent, which launched the careers of stars including Susan Boyle, Paul Potts and Diversity, will return to the small screen in the spring.
