Emma and Reggie will be co-hosts of BBC One's brand new show, Prized Apart, which will be filmed on location abroad and in the UK.
Prized Apart will feature 10 contestants who compete in a range of gruelling challenges.
Each week, the bottom placed contestants will be flown back to the UK to a studio hanger, where their partners await.
The stay-at-home partners must keep their loved ones in the competition by answering a set of questions in a head-to-head round against other partners. If they succeed, their loved ones will get back on the plane to continue the game.
Emma, who is also returning to our screens next year as co-host of The Voice UK, said: "Prized Apart will be nail biting, emotional and full of energy.
"I'll be there with the partners in the studio as they watch their loved ones go through their hellish challenges in mystery locations abroad. It should be lots of fun to see how far the contestants will go for their loved ones. I can't wait to get stuck in."
Meanwhile, former Voice UK host Reggie said he was "thrilled" to be joining the show, adding: "It's going to be an incredible experience and I can't wait to get started."
Prized Apart will air on BBC One in Spring 2015.
