Michael Buble dropped a few details about his forthcoming album, Nobody But Me, in an interview with ET Canada this week.
The 40-year-old singer revealed that Meghan Trainor and Harry Styles penned the title track off his upcoming ninth studio album, which is set to debut on Oct. 21.
"For the first time ever, I've recorded an original [song] that I didn’t write," shares the four-time GRAMMY winner. "It's written by Meghan Trainer and Harry Styles."

Fans may be surprised that Buble commissioned the work of pop stars like Trainor and Styles, but in putting the album together he felt it necessary to step outside of his musical comfort zone.
"They’re talented, they wrote a song that I fell in love with, and that was it," he explains.
"Nobody But Me" is a genre-bending collaboration in all aspects, in that it was written by two pop stars, and features hip-hop artist Black Thought, of The Roots.
As for Trainor, who wrote Jennifer Lopez’s recent single, "Ain't Your Mama," Buble couldn't stop praising the Boston native.
"I think she’s probably the most talented 21-year-old in the world," he gushed. "Listen, she’s a great singer and a great entertainer, what [people] may not know is what an incredible writer she is, what an incredible musician she is, [and] the fact that she’s a bada** producer."

The new album marks Buble's return to music, after canceling several performances to undergo vocal chord surgery in May. The minimally invasive procedure puts him in the same category as Sam Smith and Adele, and he couldn’t be happier to join the club.
"I'm like one of them now, so I have to like put myself in that echelon," Buble joked to ET Canada. "I probably would’ve gotten the surgery even if I didn’t need it."
