Comedian Bill Bailey and Invictus medallist JJ Chalmers are the latest additions to the Strictly Come Dancing 2020 line-up.
Bailey, a stand-up comedian, actor and musician is known for appearances on TV shows like QI and Black Books.
Speaking to Zoe Ball's BBC Radio 2 breakfast show, Bailey said his dance history was a "little patchy".
Chalmers is a former Royal Marine who became a sportsman, after sustaining injuries while serving in Afghanistan.
"My whole life is defined by facing challenges," he said. "Strictly is a whole different ball game... but I'm up for an adventure and at least my mum will know where I am!"
Chalmers, who has also helmed TV and radio coverage of the Commonwealth Games and the Paralympics, is the eighth contestant to be confirmed for Strictly's 18th series, with more names expected later on Thursday.
The 2020 series will begin in October but will be shorter than usual, and judge Bruno Tonioli will have a reduced role amid coronavirus restrictions.

JJ Chalmers' career as a Royal Marine Commando was cut short after he suffered life-changing injuries following an IED explosion in Afghanistan.
The blast crushed an eye socket, burst his eardrums, destroyed his right elbow, blew off two fingers on his left hand and left holes in his legs.
After years of rehabilitation, including more than 30 operations, he went on to compete in the 2014 Invictus Games where he captained the Trike Cycling team and took home three medals.
He later embarked on a career in broadcasting, presenting coverage of the Rio Paralympics and anchoring BBC One's coverage of the Invictus Games.
Comparing Strictly to his military experience, he said: "This is completely off the chart and it's going to be a huge challenge but I'm really looking forward to learning something new".
Despite his injuries, Chalmers said wanted to be treated like "any other contestant" and didn't want any "special treatment".
"Whoever I partner with they've got their work cut out," he told ITV's Lorraine.
Comedian Bill Bailey was announced as the seventh star to strap on his dancing shoes.
The offbeat stand-up comedian, comic actor and musician is known for appearances on TV shows like QI, Black Books and Never Mind the Buzzcocks.
"In these strange times we're living through, it feels right to do something different and take on a new challenge," he said in a statement.
"I haven't been to stage school and learnt to dance. I haven't lived for the dance... I'm not really Lord of the Dance. I'm caretaker of the dance," he joked. "It's going to be quite a challenge but then that's what this is about, taking on a new skill."
Bailey, 55, made his name on the stand-up circuit before becoming a regular panel show guest, TV and film actor, documentary presenter, and host of the BBC sketch show Is It Bill Bailey?
He is also a classically-trained musician and has published a guide to British birds. On Wednesday, in a review of his first live gig for six months, The Daily Telegraph said he "remains one of the funniest, most brilliantly original comedians in the UK".
Clara Amfo, who hosts BBC Radio 1's late morning slot, aid she "couldn't wait to fully embrace" the experience of Strictly.
In recent years, Amfo has presented coverage of Glastonbury, the Brit Awards, Radio 1's Big Weekend, the Bafta TV Awards and The Proms.
"As we know this year has been a real challenge and escapism through dancing is something I know we all enjoy," she said.
"So to be taught by a pro and live a fantasy is something that I can't wait to fully embrace, see you on the dancefloor!"

Singh said she felt "complete terror" at the idea of taking part, likening it to "embarking on a rollercoaster".
She previously worked as a producer and reporter for the BBC for 12 years, and presented BBC North West Tonight.
Singh said: "The initial feeling of being confirmed for Strictly is one of complete terror - feels like embarking on a rollercoaster, where you really want to do it but you are equally scared.
"Hopefully after the first dance I will feel exhilarated rather than sick!"

"Strictly was the first show I ever watched when I moved to the UK and I'm a massive fan. My six-year-old daughter never got the chance to see me run out on the field at an NFL game but she is very excited about me taking to the dance floor. I hope I can do her proud."

His former bandmate, Jay McGuiness, previously won Strictly Come Dancing in 2015.
George said he was "buzzing to be on Strictly this year", joking: "I'm not really one for the dance floor, but I take a lot of comfort in the fact that Jay McGuiness set The Wanted's bar so low."
The Wanted had two number one singles in the UK - All Time Low and Glad You Came - with the latter reaching the top three in the US Billboard chart.
After The Wanted took a break, Max moved to Los Angeles to pursue an acting career and starred in the sixth season of Glee as Clint. He recently returned to music as a solo artist.
