Mariah Carey apologizes to Shawn Mendes for mixing up messages

US singer Mariah Carey has apologized to pop star Shawn Mendes after mistaking him for her cousin in an “inside joke” news story.

The All I Want For Christmas Is You artist said she has a “silly” tradition with her cousin where they exchange happy Thanksgiving messages on St. Patrick’s Day.

However, earlier this year, the 52-year-old singer-songwriter accidentally texted Canadian musician Mendes instead of her cousin, who both share the same first name.

After realizing her mistake, Carey texted him, “Wrong Shawn. We’re sorry. I also realize it’s NOT Thanksgiving. Haha.”

Mendes, 23, replied: “Hahahaha that’s okay I thought it was an inside joke,” adding two red love hearts.

Carey shared details of the bug on Twitter, adding, “My cousin Shawn M and I have this silly joke where we say Happy Thanksgiving to each other on St. Patrick’s Day, @ShawnMendes figured it out today…sorry Shawn!!”
