Simon Cowell appeared to be in a cheerful mood as he met his Britain's Got Talent costars Amanda Holden and Bruno Tonioli at the London Palladium on Wednesday.

The 64-year-old music mogul was greeted by fans as he arrived at the theater to open the first day of live auditions for the ITV talent competition.

He cut a casual figure in a black long-sleeved T-shirt and dark blue trousers, while looking comfortable in dark trainers.

Simon framed his face with his signature aviator sunglasses and carried his essentials in two brown and black laptop-style bags.

He was joined by fellow judge Amanda, 52, who looked effortlessly stylish in white trousers and a blue ruffled blouse.

She kept warm in a chic cream jacket and gave herself a few extra inches in a pair of high heels as she stowed her belongings in a small white handbag.

Amanda protected her eyes with oversized sunglasses and appeared to be in good spirits as she laughed and smiled upon arrival.

Choreographer Bruno, 68, also made a low-key appearance, wearing a gray tracksuit which he teamed with a faux leather jacket and a scarf.

He wore a pair of black boots, a gray baseball cap and sunglasses and waved to fans as he arrived.

The fourth and final judge, Alesha Dixon, was nowhere to be seen as her fellow judges filed into the prestigious London venue.

Presenter Ant McPartlin was also spotted arriving at the venue, cutting a relaxed figure in an all-black ensemble before filming.

He returns once again to headline the talent show alongside Declan Donnelly as another year of auditions begins.

The judges and presenters have a busy few days ahead of them as contestants will flock to the London Palladium to showcase their talent in a bid to make it through the show.

They started the castings on Wednesday afternoon and will complete two blocks of casting shows per day in a packed schedule until Sunday.

They then travel to Manchester in early February where they audition for a further five days at the Central Convention Centre.

The release date for the upcoming 17th season of Britain's Got Talent has not yet been set.

While UK auditions have just begun, Simon has been appearing on new spin-off show America's Got Talent: Fantasy League in recent days.

In the new show, the judges coach all-star acts from across the Got Talent franchise, with the winner receiving a grand prize of $250,000 and their coach also being named champion.

And on Monday's episode, Simon hit his Golden Buzzer for the Sainted Trap Choir after their incredible cover of Prince's Purple Rain.

The mentor had worked with the Charlotte, North Carolina group to get them the coveted permission to sing Purple Rain.

Luckily, the night before their performance, they finally learned that Prince's estate had made an exception and given them permission to perform Purple Rain.

The group impressed the judges with their performance of the iconic song and received a standing ovation for the number.

“Mic drop,” said host Terry Crews, while Howie Mandel added: “It was amazing!” and Mel B gushed that they were “brilliant.”

“I’ve connected with you since the first audition,” Simon said. “Then we talked on the phone and I said, what would you think about singing my favorite song of all time, Purple Rain? I just heard that scream.

“And I thought, 'That's a yes.' I think Prince is the greatest artist of all time. And you said it would be fine. That wasn't it. It was amazing.'

Simon said he hoped the moment would change their lives before getting up and hitting the Golden Buzzer, sending them straight to the final.

Golden confetti rained down around them as they hugged, seeming completely overwhelmed by the occasion.

In the spin-off show, the judges act as mentors for hand-picked acts and can use their Golden Buzzer to either advance one of their own acts to the finals or steal an act from another coach and promote them to the finals at the same time. Each of the participants competes for the grand prize of $250,000.
