The pair are reportedly planning to walk down the aisle in 2019 a source tells TMZ.
“Justin’s been in love with her for a long time, so this didn’t just come from out of the blue,” says the insider.
Another source also revealed that the pair have been together longer than we realise, with the two getting back together multiple times previously that no one knew about.
E! News also reports that the pair are hoping to have both families heavily involved in their big day.
"They want to be married next year,” says a source. “They are having both of their families be very involved in the process and do not want to make a huge deal out of the celebration. It will not be an over-the-top wedding."
Hailey’s aunt, Kim Basinger, has also revealed who will be in her bridal party on her big day.
“Oh, it’ll be fun,” she told Us Weekly. "Alaia [Hailey’s sister] and Ireland [Hailey’s cousin], they’re in the wedding. So believe me, it’s cool! I think it’s sweet. It’s a very sweet thing."
