The 'Hello' superstar was being interviewed by Chris on his BBC Radio 2 show on Friday morning (23 October) when he quizzed her about the alter ego she had supposedly created to battle stage nerves.
A confused Adele replied: "No… not really. I mean, I chat a lot."
Chris then said, no, he had an actual name for her alter ego, to which clever Adele guessed he may have been talking about Sasha Fierce, the on-stage persona of Beyoncé.
Bursting into laughter, she said: "That's Beyoncé! I wish I was Sasha Fierce! Who is now Mrs Carter.'

Adele spent all morning visiting radio stations in London to launch new song 'Hello', her first track since the epic 'Skyfall' was released three years ago.
An accompanying six-minute music video was released to Vevo this morning.
Adele's new album, 25, is released 20 November.
