Hawkins and Wall wed in 2013, after dating for eight years. The couple held a small ceremony in a resort on the island of Bali. The couple were engaged for 18 months after Wall proposed in New Zealand
The couple has in the past spoken about how their relationship has strengthened over the years.
"That’s what happens when you are young and you break up a million times and then you come back together," she told Stellar.
"We’ve had a lot of downs, I guess, with Jake’s mum passing away and a few things happening in my family, so it hasn’t been perfect."
In between modelling jobs, the couple shares a project together as they launched an alcoholic beverage called Sesión Premium Tequila.
Congratulations to the parents-to-be!
