According to TMZ, which first reported the news, the 24-year-old star popped the question at a resort in the Bahamas on Saturday. Bieber's security team reportedly asked all the guests to put their phones away, keeping the moment contained to the people in the room.
They say Justin then proposed in front of everyone.
The couple, who dated in 2016 before splitting, had stirred chatter among fans in recent weeks appearing together and sparking speculation that they had reunited. Bieber famously dated Selena Gomez from 2010 to 2012 and sparked rumors of a reunion with her past year.
Oh, and Justin Bieber's mom, Pattie Mallette, posted "Love Love Love Love Love Love." on Twitter yesterday.
User @kaitpennington tweeted, "If Justin Bieber really is engaged to Hailey Baldwin. She honestly can't believe it. Selena didn't think they were even that serious, so the thought of them getting married is just mind-boggling to her", the insider said.
Bieber and Baldwin have recently spent time together in Canada, New York City and the Hamptons on Long Island, New York, where they were photographed kissing and holding hands. Everybody knows that at a certain point in time that turned into something else, but that just happens when you're 18, 19.
'We didn't speak for quite some time and there was a lot of weirdness that went on, ' she continued.
