Jaime Winstone launched her acting career in 2004 and her film credits include Bullet Boy, Tomb Raider and Wild Bill, as well stage productions such as 2:22 A Ghost Story.

The actress, who also won acclaim for her portrayal of Barbara Windsor in the BBC biopic Babs, said she was "so excited" to be joining the dance competition.

The actress said in a statement she was "no stranger to a dance floor", but added that ballroom is "a whole new world for me".

"I love a challenge though," she continued, "so can't wait to enter my showgirl era and get super sparkly!"

Winstone has also appeared in TV series such as Poirot, Dead Set, Torvill & Dean, Mad Dogs, Count Abdulla and Four Lives.

After playing Windsor in Babs, Winstone stepped into the late actress's famous role of Peggy Mitchell in EastEnders, appearing in flashback specials, most recently in the soap's 40th anniversary last year.

Dame Sarah said she "can't wait to get started'

Known as Great Britain's most successful Paralympian of all time, Dame Sarah Storey has secured 19 gold medals across the nine Paralympic Games she competed in.

The swimmer and cyclist said embarking on the challenge is "hugely exciting" and she "can't wait to get started".

"I have always loved watching Strictly and my daughter Louisa is a very talented dancer, so to be able to learn from the best and hopefully understand even more about her world, is incredibly motivating!" she said.

The former athlete won four golds at London 2012. She started her career as a swimmer and later switched to cycling, winning 30 Paralympic medals in total.

Best is known for hosting Big Brother with AJ Odudu on ITV since 2023, and as host of the Hits Radio Breakfast Show alongside Fleur East and James Barr.

He said it was "an absolute dream" to be taking to the BBC One contest's dance floor in September, "albeit a pretty terrifying one".

Best added: "I've been lucky to do lots of live telly before, but absolutely nothing like this. And I cannot wait!

"I have no idea if I can actually dance, but bring on the sequins, bring on the quicksteps, bring on the dance floor! I'm going to try to enjoy every minute of it."

Mercer was part of the winning couple on ITV dating show Love Island last year, and also works as a model and DJ, and is an ambassador for a young people's mental health charity.

"I have grown up watching the show with my family and am so excited to now be part of the cast," he said.

Mercer also showcases his Afrobeat, hip-hop and street dance moves on his social media accounts.

"Dancing is a huge passion of mine and I can't wait to learn ballroom and do the foxtrot for the first time!" he added.

Delta Goodrem is also part of this year's celebrity list, with the Australian singer and actress becoming the third celebrity to be announced for the upcoming series.

"I've been incredibly honoured to perform on many different stages throughout my career - from TV, theatre, film sets, to touring my own shows around the world," Goodrem said.

"There is, however, one stage I've never stepped onto and that is the ballroom floor. I'm absolutely thrilled to be joining Strictly and can't wait to get started."

She rose to fame in hit Australian soap opera Neighbours and recently represented her nation in the 2026 edition of the Eurovision Song Contest.

Celebrity hair stylist Chris Appleton is also part of this year's line-up.
