Smith started dating fitness model Jamie Villamor sometime in 2017. Though the pair remained relatively private about their relationship, they made rare appearances now and then. The 40-year-old model supported her then-beau by accompanying Smith to the Los Angeles premiere of "Sharp Objects" in 2018. Villamor left a gushing comment on the actor's Instagram, writing, "You are 🔥 I'm so proud of you."
The couple were present at the Route 91 Harvest musical festival on Oct. 1, 2017, when the Las Vegas mass shooting took place. Villamor shared an Instagram post detailing her experience. "Thank you for all the amazing messages. extremely grateful this evening for the safety of my loved ones. It saddens me that others were not as lucky #prayersforvegas," she captioned the post. "He is the blood in my veins, the passionate flames that ignite my drive to persist, & reminds me why I exist. ❤️ to my love that was brave enough to keep me safe & help those around us that had been shot."
The couple dated for around two years, attending the 11th annual Fighters Only World MMA Awards in July 2019. They also showed up at the star-studded Podwall Entertainment's Halloween party in sexy police-officer costumes in October later that year.
The couple seemingly broke up by the end of 2019. Though neither ever confirmed the breakup, their eventual lack of involvement in each other's lives on social media (where they were once very public about their relationship) suggests they parted ways sometime in late 2019.
