The former White Stripe told BBC 6 Music that Thom Yorke and co. spent some time in the studio owned by his label Third Man Records but insisted that he didn't contribute in any way.
Rumours of new Radiohead material have been rampant since Thom Yorke cryptically announced that he had some exciting plans in the pipeline at last month's Bonnaroo Music and Arts Festival in the US.
When pressed on Radiohead's time spent in his studio, White said: "I don't know how much to tell about it except I didn't play with them or produce."
"But they came in and recorded at Third Man. I don't know what else to be said about that, so that's all I can probably say", he added.
