The Kaiser Chiefs star previously said he was left a little starstruck when he joined the show this year alongside fellow new coach Kylie Minogue.
But while Ricky quickly hit it off with Kylie and Sir Tom Jones, he found Will harder to understand.
"Will's trickier. He likes to play with intelligence," Ricky told The Sun on Sunday's Fabulous magazine this month. "Once he was saying that DNA was going to become currency and I was trying to work out what it meant. I'm still working it out!
"It was only when I realised he likes to wind you up that I started getting along with him."
Ricky says things were a lot easier with Sir Tom and Kylie and told how the trio have enjoyed dinners and topless dressing room parties together!
"Kylie emailed this week," Ricky said, like it totally wasn't a big deal. "She was going to Paris on the day I was leaving, so we were emailing about going for dinner.
"She likes Jamie's Italian. I think I'll treat her soon ... I get more joy telling me people about [the celebrity lifestyle] than I actually get from it!"
Ricky added: "I've been out for dinner with Tom and spend a lot of time in his dressing room too ... with his top off!"
