Former home secretary Jacqui Smith has been confirmed as the 12th and final celebrity contestant on this year's Strictly Come Dancing.
Smith will join with stars including Bill Bailey, Clara Amfo, and HRVY.

The BBC also confirmed they will be able to rehearse, perform and go home to their family each night - following government guidelines.
Jacqui Smith was confirmed as the final celebrity dancer on Steve Wright's Radio 2 show on Friday afternoon.
The former Labour politician became the UK's first female home secretary in 2007 - under then-Prime Minister Gordon Brown - and has since worked as a political broadcaster.
"I was speechless with excitement at being asked to join Strictly - and that's very rare for me," said Smith.
"Fifty years ago, I got a bronze medal for Scottish Highland Dancing and it feels about time to return to dancing."
"I couldn't be in better hands with the Strictly team and I'm going to throw myself into the challenge. Watch out!" she added.
Smith is now the chair of the University Hospitals Birmingham NHS Foundation Trust and Sandwell Children's Trust. She also has a podast, called For the Many, that she presents with broadcaster Iain Dale.
HRVY was revealed as a contestant on the Kiss breakfast show and said he was "so thankful to be taking part".

He also founded the sweets brand, Candy Kittens, in 2012.
"Here we go again, hopefully this time I can last long enough so my mum can see me dance," said Laing.
He added: "The reason I'm doing it, is to make my mum proud but all I did last year was make her even more disappointed. Let's change that this year, can't wait!!"

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 told ITV's Lorraine: "I'm always looking for a challenge, I'm always looking to push myself outside of my comfort zone."
Despite his injuries, Chalmers said he 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 added.
Bill Bailey is an comedian, actor and musician is known for appearances on TV shows like QI, Black Books and Never Mind the Buzzcocks.

"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".

"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!"

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!"
