Hailey Baldwin, $500,000
Having first met during a fan event in 2009, Hailey Baldwin and Justin Bieber attempted to dispel dating rumors in 2014 when they were spotted leaving church before spending a romantic New Year’s Eve together in 2016. It was until July 2018 that Bieber popped the question with an oval-cut diamond ring estimated to be worth “around half a mil” according to TMZ.
