The Weeknd turned heads by showing off his new look including a mustache at the Toronto International Film Festival.
One of the people who had a hilarious reaction to the new facial hair was Bruno Mars.
Mars posted a picture of him looking a little confused on Instagram with the caption, "This was the moment I saw The Weeknd's New Mustache."
When a fan posted a picture of Bruno and The Weeknd sporting staches on Twitter, Mars responded, "It's on now!"
