The singer has apparently been spotted around the Worthy Farm site already this weekend, with some reports suggesting she is planning to make an appearance early on Sunday morning.
A source is quoted as saying: “She’s been saying to Mark for ages that she wanted to come to Glastonbury again. Mark is playing officially in the early hours of Sunday morning but they are trying to make another set work because she is due back in the States to meet the Dalai Llama on Sunday.”
If Gaga were to appear it would be the first time she had performed at Glastonbury since 2009.
Recently, Ronson posted a photo of Parker and Gaga on Instagram causing speculation that the trio were working together.
