The two pop stars grabbed the internet's attention this weekend when the 20-year-old Canadian singer shared The Observer Magazine's new cover, dubbing Mendes "Prince of pop."
"Thank you @obsmagazine," the star shared on Instagram.
The title did not go unnoticed by the Biebs, who playfully called him out. "Hmm ' Gonna have to break a few more records to dethrone my title there bud (canadian voice)..but if you want we can play hockey for it but i heard your a real bender on the ice we could just drop the buckets and tilt for it," Bieber wrote in a comment. In fact, Bieber had been named "Prince of Pop" on a cover of Hero back in 2015.
Mendes took the comment in jest, writing back, "LOL any time any day you just let me know!!!!!!"
