The pair made their debut as Big Brother presenters in October 2023.
A source told The Sun of their return for the celebrity version: "There was huge pressure on AJ and Will's shoulders when they launched ITV's reboot of Big Brother but they've absolutely risen to it.
"Both had experience but this felt like a really big job and there were whispers ITV might've been better choosing a pair of safe hands like Big Brother legends Davina McCall or Rylan Clark.
"Will especially hadn't been on a proper prime-time production for a good few years, but it's already hard to imagine the show without them."
