Adele declined to donate a song from her Glastonbury festival performance to a charity album raising funds for refugees and dedicated to the memory of MP Jo Cox.
Fellow headliners Muse and Coldplay, plus Jess Glynne, Years & Years and Wolf Alice were among the acts to dedicate tracks from their live sets to album Oxfam Present: Stand As One - Live From Glastonbury 2016.
However, the 28-year-old turned down the offer to add one of the tracks from her lauded Saturday night set to the album, profits from which were split between Oxfam's work with Syrian refugees and the Jo Cox Fund, set up in memory of the Labour MP who was shot and stabbed to death.
A spokesman for the Hello singer said: "Yes, she was approached but Adele chose to support the cause by donating privately to refugee charities and privately to one of Jo Cox's chosen charities."
A spokeswoman for Oxfam added: "We are thrilled that Adele is responding to the refugee crisis by donating directly to the cause. However we do it, we 'Stand As One'."
There were reports back in 2014 that the mother-of-one had snubbed the chance to take part in Bob Geldof's Band Aid 30 charity cover of Do They Know It's Christmas? to fight Ebola but the Boomtown Rats frontman denied it.
He said: "I didn't call Adele at all because I don't have her number. There is no snub...it's nonsense. Complete nonsense."
Adele, who is worth a reported £85 million, revealed she was "mortified" recently when her credit card was declined at H&M.
