Jungle winner Swash has hosted the nightly spinoff alongside Caroline Flack since 2009, while comedian Kane has also worked on the programme before.
Whitmore is best known as a presenter on MTV Europe. She said: "I'm absolutely thrilled to be joining the I'm a Celebrity... family. I can't wait to get stuck into jungle life, though I will try my best to avoid all those creepy crawlies.
"I'm really looking forward to getting into all sorts of mischief and mayhem with Joe and Russell. The excitement level is officially off the scale!"
Meanwhile, Kane joked: "I'm as stoked as a Victorian fireplace to be going back jungle-side. Sharing a cabin with Joe; what's not to love? And as for Whitmore... phwoar!"
Ex-EastEnders star Swash added: "I'm really chuffed to be part of the team again this year and I can't wait to be reunited with Russell again and this year we've got sexy newbie Laura joining us - now all we need to know is the lineup!"
I'm a Celebrity... Get Me Out of Here is expected to return for its 11th four-week series from November on ITV1.
Dannii Minogue, her boyfriend Kris Smith, Kerry Katona, Alex Reid and Jedward are amongst those linked to the show's lineup.
