Just a year after Justin Bieber asked the infamous "who's Shawn Mendes?" question during a radio interview, the "Love Yourself" singer is sharing his support for Mendes' new album Illuminate. 

On Wednesday morning (Oct. 5), Bieber released a series of tweets praising the 18-year-old Canadian singer by saying his voice "makes me smile. Truly a gift to be able to move people's emotions through songs!"

Mendes tweeted back his full appreciation and gratitude by thanking Bieber.
