TMZ reported the singer proposed to his girlfriend Saturday night at a restaurant in a resort in the Bahamas.
Bieber and Baldwin, 21, have been a couple for about a month after previously dating and breaking up over the past couple of years.
Bieber’s parents posted social-media messages that are being interpreted as confirmation, as well.
“@justinbieber Proud is an understatement! Excited for the next chapter!,” Jeremy Bieber captioned a photo of his son looking out at the ocean at sunset.
“Love Love Love Love Love Love Love,” his mom Patti Mallette tweeted.
