Wil is one of those people that prefer to keep their business and personal lives apart, although he has revealed some information about his wife to the public.
Willis met his wife Krystle Amina while still a member of the Air Force Pararescue team, and the two began dating after meeting in a pub. Wil proposed to Krystle on 24 March 2017, and they exchanged wedding vows on 10 October 2017 at “The 1909” event venue in Topanga, California – only close friends and family attended. They then went to Hawaii for their honeymoon.
Wil and Krystle do not have any children, however, on August 7, 2019, he announced on Instagram that his wife is pregnant. He appears to have two boys, Caleb and Jacob, with a lady he dated – and, according to some stories, married – before Krystle, and he is frequently heard talking about them; it appears that his sons get along well with Krystle, as they both attended the wedding.
