Justin Bieber Engaged!!

Justin Bieber popped the question to Hailey Baldwin Saturday night … so claim 2 eyewitnesses.

The 2 women who say they saw the engagement go down claim it was at a resort in the Bahamas.  They say everyone was at a restaurant on the property doing salsa dancing when Justin’s security told everyone to put their phones away, because something special was about to happen.

They say Justin then proposed in front of everyone.

Another source with knowledge of the situation also also confirmed to TMZ that Justin and Hailey did, in fact, get engaged Saturday night.

Justin and Hailey have been almost inseparable since they began dating about a month ago.  They’re no strangers to each other … they’ve dated before, and it appears they hooked up again just after Justin and Selena Gomez broke up.

Justin’s dad, Jeremy, posted a photo of his JB Sunday with the caption, “@justinbieber proud is an understatement!  Excited for the next chapter!”
