The Take That hitmaker is close friends with the group and even performed with them while they were contestants on The X Factor in 2010. Possibly hoping to indulge in Robbie's boyband experience, the group say he is welcome to join them on stage again anytime.
"That is amazing. We are actually massive fans of Robbie Williams. And after singing on the show with him and stuff," Louis told Capital FM.
"He can join us anytime. [The] invitation is there."
Meanwhile, Zayn added: "He can join whenever he wants - he knows that. It's cool."
We're thinking Robbie may look a little like grandad next to the younger boys!
