Justin Bieber and Hailey Baldwin
Many people were shocked when this famous pair announced their engagement. When Hailey Baldwin was just 12, Bieber met his future wife at a fan event. They first met in 2016, but after several family trips, the relationship quickly fell apart.
After a brief reunion with an old flame, Bieber and Baldwin were back together again in July 2018, just two months after rekindling their relationship. They got married three months later in New York for a private ceremony.
