Apparently, Hilaria Baldwin likes some good music!

She was listening to the song “Back At One” by Brian McKnight.

“It’s an exquisite torture,” Alec wrote in the caption of his Instagram video.

Hilaria shared the story to her Instagram page as well.

“Gave Alec a 90s night music history lesson,” she explained.

“Part of the age gap we have…he DIDN’T KNOW THIS SONG!!!!!” she revealed.

Hilaria was born in January 1984, so she’s 38.

Alec Baldwin was born in April 1958, so he’s 64.

Most fans probably didn’t realize there was such a big age gap between them!
