Coincidentally, Humes' husband Marvin is a co-host of rival BBC show The Voice, from which Ora has been poached. The couple are regular presenters and have worked together on ITV's This Morning, while Rochelle hosts ITV's Ninja Warrior UK with Chris Kamara and Ben Shepherd. 

Odoom previously worked on The Brit Awards for ITV2.

"I have watched The Xtra Factor for years so I am beyond excited about joining such a brilliant team and getting to work with my old friend Melvin makes it even better," said Humes in a statement.
