Hailey Baldwin has bought her fiancé Justin Bieber his own engagement ring. 

The 'Sorry' hitmaker popped the question to the 21-year-old model with a diamond sparkler over the weekend following years of on/off dating but, although it's usually only the female who wears the bling, the blonde beauty didn't want her beau to feel left out so reportedly splashed out on a dazzling jewel for him when they stopped by Pristine Jewelers in New York City on Tuesday, July 10, according to The Blast.

A source told the publication: "Hailey purchased a diamond-encrusted ring with the initials 'JB' for Justin to wear, along with another custom made diamond ring for herself emblazoned with 'Baby.' It’s unclear if it's a nod to his 2010 hit song."

While the couple were there, Hailey dropped off her engagement ring to be resized as it was a little too loose for her fingers and have a few more diamonds put in. 

The 24-year-old pop star reportedly got down on one knee and asked Hailey to marry him in front of a crowd while they were on holiday in Baker's Bay, Great Guana Cay. 

A source said at the time: "Justin made arrangements for the ring when they were in NYC and knew that he wanted to propose to her. It was a sudden decision, but Justin always knew Hailey and him had a special bond that was incomparable."

And less than 24 hours after he slipped the engagement ring on Hailey's finger, Justin confirmed the news by sharing a gushy post about his love for her on Instagram. 

He wrote: "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! The thing I am most excited for is that my little brother and sister get to see another healthy stable marriage and look for the same!!!
