The 'Rumour Has It' singer chooses to wear her sleepwear and tracksuit bottoms whenever she needs to walk through busy London in order to avoid being noticed.
"I've managed to stay out of the public eye recently," The Sun quotes her as saying.
"The other day I walked through Trafalgar Square. I was in my pyjamas. I had floral tracksuit bottoms on, a green coat and pink pumps.
"Luckily I had a massive umbrella so no one recognised me."
Adele was recently rumoured to be looking for a new London home at a cost of around £10 million.
The singer-songwriter has also denied reports that she has become engaged to boyfriend Simon Konecki.
