Congratulations to Randy Houser and his singer-songwriter girlfriend, Jessa Lee Yantz, who tied the knot last week.

According to PEOPLE, Houser and Yantz said "I do" in a very intimate ceremony on Friday, September 2, consisting of 20 of their family and closest friends.

Both the bride and groom exchange self-penned vows during the ceremony, which took place in Punta Cana, Dominican Republic. Houser's close friend and hit songwriter Rob Hatch married the couple in a breathtaking sunset ceremony.

Following their tender vows, Houser and Yantz sang an a cappella version of 'Have I Told You Lately That I Love You.'

Houser, 34,  announced his engagement to Yantz, 29, in July. After his proposal, the couple customized her 300-diamond engagement ring with a jeweler to reflect the bride's style. The completed piece is composed of almost 5.5 carats of brilliant-cut diamonds, set in 18-karat gold with a double diamond halo.

"I finally found the person that I can't be without," Houser told PEOPLE after their engagement news broke to the media. "Jessa makes me a better person every day, and I look forward to spending the rest of my life with her."

"I'm a good hearted woman lovin a good hearted man," Yantz tweeted this summer. "Now THAT'S a match made in heaven."

Congrats to the beautiful couple!
