REVEALS: Charlie Puth finally reacts to Taylor Swift name-dropping him on ‘The Tortured Poets Department’…

Taylor Swift name-dropped Charlie Puth in a song featured on her her latest album, “The Tortured Poets Department,” last month, and he finally reacted — with a song of his own.

“My new song HERO is about when you see someone you love hurting themselves, ruining the things in their life that are good, but you just can’t save them,” Puth, 32, told his Instagram followers Tuesday.

He called the release “one of the hardest songs” he’s ever written.
