It finally happened, you guys! Kailyn Lowry of Teen Mom 2 tied the knot today (September 21) in Camden, New Jersey. She married boyfriend Javi Marroquin in a romantic under-the-sea-themed wedding, reports In Touch.

The couple technically got hitched last year but held off on hosting a ceremony and reception, the magazine explains.

"We wanted to have a wedding last year when we were married, but obviously with him in the Air Force, we weren't able to," Kail told In Touch. "Now, we got to do it front of our family and friends!"

Beside planning a wedding, Kali’s been busy preparing for her next big project: her new baby! That’s right. The Teen Mom star is in her third trimester with her second bundle of joy. The mom finally made the announcement earlier this month, tweeting, "Yes, @JaviM9 and I are pregnant. But we definitely don't know the gender. No matter what people will always say we don't deserve privacy or assume we just don't want it. Definitely unfair!"

Kailyn's latest tweet shared equally good news: “IT'S OUR WEDDING DAY! @JaviM9.” Javi shared his excitement via social media, too: “I'm on 3 hours of sleep but idc CAUSE IM GETTING MARRIED TODAYYYYY.”

We bet Isaac made an adorable addition to the bridal party! Congratulations to the happy family as they start this next chapter.
