The actor appeared on a recent episode of Sirius XM's The Jess Cagle Show,

where he explained that his three daughters, Betty, 3, Inez, 6, and James, 7

never put together that mom and dad’s close friend and someone

they called an “aunt” was actually the biggest musician in the industry.

“I think what's most exciting for them is that for the longest time they just thought Taylor's just like an aunt,

like a friend of Mommy and Daddy that's very, very close, almost family,” he explained.

“And then they went to a concert one day and were like, ‘Ohhhhh, this isn't a hobby,’” Reynolds joked.

He also shared that the girls planned a "Midnights dance party" when Swift

dropped her new album, Midnights.

We're headed straight to the porch where we're doing a full dance number set to Midnights,

swear words included,” he said
