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.

Charlie Puth responds to Taylor Swift shout-out, thanking her for inspiring him to pen "one of the hardest songs" he's ever written

“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.

Charlie Puth finally reacted to Taylor Swift name-dropping him in her song.

Her confidence has inspired Puth’s upcoming single, “Hero.”

“I wrote it hoping that you’ve gone through something similar in your life, and that it can fill in the BLANK for you like it did for me,” he continued. “I’m very excited to share my next album with you, especially this song because it’s a great representation of what’s to come.”

While noting that he has “never put out a song like this before,” he gave Swift, 34, a shoutout.

“It’s very different for me, but I want to thank @taylorswift for letting me know musically that I just couldn’t keep this on my hard drive any longer,” Puth gushed. “HERO is yours on May 24th and this is the single artwork.”

He called the song “different” from anything he’s released before

He concluded, “Thank you to all of my fans- you’ll never know how much you mean to me.”

Swift has yet to publicly respond to Puth’s news.

The pop star released her 11th album, “The Tortured Poets Department,” on April 19, and the record’s titular track references Puth.

Swift’s “TTPD” album came out last month

“We declared Charlie Puth should be a bigger artist,” she sings.

Puth subtly responded to the lyrics at the time by re-posting a photo of Swift’s to his Story, in which she referenced the track.

The song, overall, is believed to be about her relationship with ex Matty Healy.

With “So Long, London” purportedly being about Joe Alwyn, Swift’s 35-year-old boyfriend, the vocalist of 1975, wasn’t the only one who appeared to be named on the album.

Swift also made an appearance to sing in “The Alchemy” and “So High School” about her current beau, Travis Kelce.

Since last summer, she has been dating the 34-year-old tight end with the Kansas City Chiefs.
