"Was gonna wait a while to say anything but word travels fast, listen plain and simple Hailey 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. 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. My heart is COMPLETELY and FULLY YOURS and I will ALWAYS put you first! You are the love of my life Hailey Baldwin and I wouldn't want to spend it with anybody else. You make me so much better and we compliment eachother so well!! Can't wait for the best season of life yet!. It's funny because now with you everything seems to make sense!

"You stick out of the crowd, baby, it's a no-brainer/ It ain't that hard to choose. Him or me, be for real, baby, it's a no-brainer."
Does this, by any chance, refer to how Justin felt about Hailey while she was spotted out with Shawn? This miiiight help explain why it all happened in such quick succession, and also why both Shawn and Hailey very quickly denied being romantically engaged—despite the fact they looked very into each other on the red carpet in May.
July 30, 2018: Wait, is the wedding happening sooner than we think?! Biebs hinted at it during a conversation with paparazzi. When asked what was next career-wise following his latest tune "No Brainer" being released, Justin flashed a grin at Hailey Baldwin, and said "What's next? Getting married."

August 14, 2018: Sources tell TMZ that Hailey and Justin aren't planning on getting married until next year, despite their quick engagement. "Justin's been in love with her for a long time, so this didn't just come from out of the blue," a source said.

September 4, 2018: In an interview with Australian Magazine Stellar, Hailey Baldwin explained how she is "beyond excited" to be engaged, and is making light work of ignoring the negativity that has surrounded her and Justin Bieber's relationship.

September 14, 2018: Everyone thinks Justin Bieber and Hailey Baldwin have already tied the knot. Here's why...
They were spotted at the Marriage Bureau in New York City yesterday, and TMZ reports that he said to a member of staff: "Thanks for keeping it on the DL."
But after Justin Bieber and Hailey Baldwin were spotted at the Marriage Bureau in New York City, everyone thought they had pulled off a secret wedding. But, in a since-deleted Tweet (as if things couldn't get any more cryptic), Hailey squashed those rumors, writing "I understand where the speculation is coming from, but I'm not married yet!"
September 19, 2018: Woah woah woah. According to Hailey Baldwin's uncle and actor Alec Baldwin, his niece and Justin Bieber HAVE married in secret, despite the model tweeting and deleting a denial of the rumors. Speaking with Access at the Emmys, Alec commented, "They just went off and got married and I don't know what the deal is."
People corroborated this last week, after a source said of Hailey and Justin's marriage, "They went ahead and did it without listening to anyone."
September 20, 2018: Hailey Baldwin sat down with Coveteur to get personal about the rollercoaster of her life, exclaiming, "Well, I got engaged. I think that's probably the biggest OMG moment of the year for me, of my life. So that's probably top."
September 23, 2018: Justin and Hailey are reportedly working on their prenup (supposing they're not yet married).
TMZ reports that both have found themselves a lawyer to work through the proceedings, with Justin apparently taking advice that it would be insane not to protect his rumored $245 million (P13.14 billion) fortune. Hailey is apparently worth around $2 million (P107.28 million).
September 25, 2018: For a while there, everyone was confused about whether or not Hailey Baldwin and Justin Bieber had already got married. But considering they're apparently working on a prenup, we're guessing they're still just engaged. Or not. Who knows...
But at least Hailey's cousin, Ireland Baldwin, seems as out-of-the-loop as we are.
In an interview with Entertainment Tonight, Ireland said: "I have no idea what their situation is.
"I think they're just taking things slow. They're just kissing all over the world. They're just kissing and loving and having fun, and I think people take little details and get too caught up in them, and they're looking too hard. Just let them kiss!"
1st September 2018: Justin has been introducing Hailey to people as his wife! Does this mean they're already married?
During a visit to the Stratford Perth Museum in Ontario, who have dedicated an exhibit to Biebs, The Windsor Star newspaper say Justin "very graciously introduced Hailey as his wife" during the visit, before the museum's official Instagram page referred to him as her husband.
Along with a photo of "I [heart emoji] you forever-Hailey B" scrawled on a chalkboard—presumably by Justin, they captioned an Instagram photo, "We were so pleased to have such a warm and special guest visit the museum yesterday (along with her very special husband). @haileybaldwin @justinbieber."
If the wedding has happened, when do we get to see the pics, please?
2nd October 2018: A reporter asked Hailey's *rumoured* ex-boyfriend Shawn Mendes if he was performing at her wedding to Justin Bieber, and the answer was just as awkward as you'd expect.
"Am I going to sing at the wedding? I, I, of course, I would sing," he stuttered. "I have not been invited yet but I'm sure something will happen soon."
Hailey and Shawn went to the Met Gala together earlier this year, and though he shared a lot of cosy looking Instagrams afterwards, Hailey clarified in an interview that they were still just friends. She told The Times UK, "We hang out and he's super-lovely and a very, very nice young gentleman, but I am single."
Hmm. Has any hanging out happened since the engagement news, though? And will he get an invite to the wedding?
18th October 2018: Er, you GUYS! Hailey and Justin apparently just confirmed to a fan that they are married. Nona Melkoni, 16, was sat beside the couple at a restaurant recently when she asked them what the deal is.
"I asked them if they were married and they simultaneously said yes!" Nona told Us Weekly. "They were both very happy and kind. He told me that she's his angel. They were super-sweet!"
