Unfortunately, the legendary jazz crooner has received strict orders not to tune into her latest project.

“Gaga told me, ‘Don’t let Tony watch it!'” Bennett’s wife, Susan Crow, told PEOPLE during the American Natural History Museum Gala.

“I told Gaga I was watching it and she said, ‘Please don’t let Tony see it – I’m serious! Don’t let him watch it!’ And now that I’ve seen some of it I’m like, ‘Oh, I understand!'”

Crow thinks Gaga’s AHS performance is just “great” – and though she says the hit show “might be a little much” for her husband, she thinks Bennett would enjoy it.

“They have a very good relationship,” Crow, 49, says of the pair. “We love Gaga.”
