While it's true that the singer wrote the dance track ‘Bienvenue’ by IAM featuring Beyonce, released in 2003, the singer is not the only Australian to have written for the star.
Fans couldn't hold back and were quick to correct Osher, tweeting that other Australians had actually written for Beyonce, too.
"Deni's the only Australian to write a song for Beyonce? Ummm, Pretty Hurts by Sia much?" one fan tweeted.
"Did @oshergunsberg just say Deni was the only Australian to write a song for Beyonce like @sia hasn't been in her basement for years," said another.
Another fan tweeted: "Deni isn't the only Australian to have written for Beyoncé" alongside a Wikipedia entry for her song Rather Die Young, which was co-written by Australian Luke Steele, of the band Empire of the Sun.
