Justin Bieber's Engagement Note to Hailey Baldwin, 'I Will Always Put You First'

Justin Bieber just broke his silence on his engagement to Hailey Baldwin ... and JB held nothing back in describing his emotions.

Justin basically wrote an open love letter to his fiancée, saying ... "I am soooo in love with everything about you! So committed to spending my life getting to know every single part of you loving you patiently and kindly."

He also talked religion and about having a family of his own, saying, "I promise to lead our family with honor and integrity letting Jesus through his Holy Spirit guide us in everything we do and every decision we make."

As for when they'll get married ... our bet is it'll be the 7th of some month. Justin points out, "We got engaged on the seventh day of the seventh month, the number seven is the number of spiritual perfection."

JB's words struck all the right chords with Hailey, who responded online a few minutes after his post.
