Adele also displayed the results of her weight loss by dancing around her living room in the same dress she wore for her headline set at Glastonbury four years ago.
The Grammy Award-winning star reflected on her legendary performance as the BBC showed highlights from past years of the festival after the 2020 event was cancelled because of the coronavirus pandemic.
In the first snap Adele shared last month, she was pictured squatting beside her television in a pair of cosy grey jogging bottoms which she paired with a white T-shirt while pointing an electronic handheld fan towards her face.
The second photo showed the singer enjoying a dance in the custom-made Chloe dress from her festival performance, while an image of her singing could be seen on the TV screen in the background.
