Gemma Atkinson has been announced as the fourth celebrity contestant.
The former Emmerdale and Hollyoaks actress was introduced as the latest Strictly star on Thursday's episode of BBC Breakfast.
Gemma admitted she felt "really bad" having to lie to her loved ones when rumours that she could take part started to emerge, as the only person she was allowed to tell was her mum.
"I can finally say I'm doing it! Sorry for lying!" she laughed.
"I'm looking forward to just learning to dance as it's out of my comfort zone. Even wearing heels for me is a big thing. Putting me in a sparkling frock is out of my comfort zone.
"I want to challenge myself and do something I've never done before.
"I did disco dancing from the age of nine to ten but that was kind of cartwheels across the floor, eat my pic 'n' mix and go home.
"As far as any dance training goes, I haven't had any.
"After a few drinks I think I'm Britney Spears but I'm not at all!"
Gemma said she has no preference for who she gets as a professional partner as long as it's someone tall enough as she's 5ft 9in.
She's best known for playing Lisa Hunter in Hollyoaks, Carly Hope in Emmerdale and Tamzin Bayle in Casualty, and has also appeared in the likes of The Bill, Law and Order and Waterloo Road.
