Lady Gaga Better Answer Her Phone

Cher is calling.

Lady Gaga better answer her phone. Cher is calling.

As evidenced by Gaga's Thursday afternoon (Nov. 5) Instagram, it looks like the singer wants to talk. But did Gaga pick up? Is she letting it go to voicemail? Did she take that picture with a second phone? Is this more than a candid photo and perhaps some clever marketing tactic? So many questions.

Gaga and Cher have definitely crossed paths before -- first, on the 2010 MTV Video Music Awards stage, when LG asked Cher to hold her meat purse ("There’s those moments you just remember [forever],” Cher told MTV afterward.)

And then there's their lost collaboration, "The Greatest Thing." Gaga and RedOne wrote a song that was given to Cher for her 2013 album Closer To The Truth. Since they couldn't agree on a final version, the public never got to hear it.

You also can't ignore how Cher-esque Gaga looked on the cover of her Tony Bennett duet album, Cheek To Cheek, which Cher loved, by the way.

Anyway, it's about time for a duet.
