Lady Gaga and Tony Bennett have been making the media rounds promoting Cheek To Cheek, the joint jazz LP they’re dropping in September. While it’s clear the singers come from different eras in popular music, just precisely how big is the age difference between the two stars?

Well, if you really want to know how many years there are between the pop diva and the classic crooner, you’ll have to hop into the gallery above. You can also discover how the pair stacks up against other musical collaborators who’ve bridged age gaps of 15 years or more. We’ve got artists like Elton John and Mary J.
