The Rolling Stones are trying to get her back on stage in a concert with them. Frontman Mick Jagger is pulling chart-topping female artists to collaborate on their tour, including Taylor Swift, Sheryl Crow, Florence Welch and Lady Gaga.
"She is the name they want to announce as their special guests -- and their invite should be special enough to get her out on stage," a source for The Sun said.
The source said that the group is trying to get Adele to be their special guest at their Hyde Park shows, which are expected to be some of the biggest of the tour.
"At the minute, it's 50/50 that she'll do it, but Mick is quietly confident he can pull it off," the source said. "They want to make the Hyde Park shows a highlight of their tour, and her appearing would make it really special."
Should Adele agree to the show, it is unclear whether she would perform as an opener or perform as a guest star with the group.
