Superstar Justin Bieber, having meteorically risen to fame during his teens, showered current teen star and fellow Ontarian Shawn Mendes with praises for his new album Illuminate. The album debuted at #1 in 65 countries around the planet, and Mendes tops this week’s U.S. Billboard Artist 100. This morning, Justin Bieber launched the tweet, “Shawn Mendes’ voice makes me smile. Truly a gift to be able to move people’s emotions through songs! So proud of you brother! Great album!” Now, 12 hours later, that statement has been retweeted 100,000 times. And, yes, Shawn Mendes replied to the tweet with the following words to his Canadian brother, “Ah man! Thank you SO much!!! Truly thank you!” Universal Music Canada must have taken note, as the nation’s biggest record label wrote, “Dearest Justin and Shawn, Please Collaborate – Signed Canada.” It would certainly be the collaboration of the decade. Justin further urged his fans (the Beliebers) to buy a copy of Shawn’s album Illuminate.
