Bieber, 24, and Baldwin, 21, had been in a relationship in 2016, before calling it off, then rekindled the romance in June this year. 

According to E! News, the singer had gotten down on one knee in the Bahamas on the island resort of Baker's Bay on Saturday (July 7, 2018), popping the question with an oval diamond sparkler. TMZ reported that the proposal took place at a restaurant, with security requesting for all patrons' mobile phones to be turned off.

But while the pair are happily in love, there's just one thing... Bieber's now signature moustache. Responding to a producer and actor Ryan Good's suggestion on Twitter for her fiance to grow his facial hair for his wedding, Baldwin had this to say:
