Moss was upset when she was not selected to appear in the singer's 1990 'Freedom' promo - which featured Naomi Campbell, Linda Evangelista and Cindy Crawford - and to make up for it Michael has asked her to appear in his latest project.
However, rather than posing alongside a group of other models in the video she will work with a zebra, reported Daily Mirror.
"Kate is a huge fan of George's and always has been. She has been to all his concerts and she was really good friends with his ex-boyfriend Kenny Goss, too. When she said last year that she was upset she didn't get to star in the 'Freedom' video, it got everybody involved in George's new track thinking.
"She was offered a cameo role in the new video as long as she could make it along to the studio for the shoot. She was delighted to be offered, and if everything goes to plan, she'll appear in it," a source said.
'White Light' was written about Michael's battle with pneumonia last year, which saw him hospitalised and close to death.
