Cher is going gaga over Lady Gaga – but she is gagging over Adele! Gaga happily stepped in to help Cher with her final career comeback album after Adele turned her down. Cher was “over the moon” when Gaga offered up the song, “The Greatest Thing,” as a duet with her her for her new album, Cher’s 26th, said an insider.

Cher first met Gaga at the 2010 MTV VMAs – at the time, Gaga was wearing a dress made out of meat.

When Cher – incensed by Adele’s snub – got the news that Gaga was going to write a song to sing with her, she tweeted that she could “hardly wait” for “The Greatest Thing” to come out. On the other hand, Cher has nothing but disdain for Adele.

“Cher would have moved mountains to get Adele to write her a song or just sing a chorus on her album, but Adele wouldn’t even return her calls,” said the insider. “Cher is acting as if she doesn’t care about Adele’s rejection, but deep down she’s absolutely fuming!”

“Cher’s thrilled that Gaga stepped up to help,” said the insider. “But she’s insulted that Adele has no interest in contributing.”

..maybe Cher got the wrong number
