The two had officially become husband and wife last September, before Marroquin left for the Air Force, but they finally celebrated their union with family and friends at the lavish bash this weekend, and RadarOnline.com has all the photos from inside their sweet ceremony.
"Kailyn and Javi shared one of their memorable dates swimming with sharks at the aquarium, so the venue was really special to them," an insider revealed.
"She's always been obsessed with mermaids and the ocean and after they went there and swam with sharks, she was set on having their wedding there."
The 21-year-old reality TV star's father was not at her wedding to walk her down the aisle because she has not spoken to him in nearly four years, an insider revealed, after the two had a major falling out while she was filming a 16 and Pregnant episode.
Also not present was Lowry's mother, who she hasn't spoken to in more than two years.
Lowry's bridesmaids wore pale lilac gowns with a sheer overlay and asymmetrical shoulder, along with purple bracelets that matched her centerpieces. The groomsmen wore lilac satin vests and bow ties, and Marroquin wore a three-piece suit with a tuxedo shirt and bow tie.
"Cannot believe last night has come & gone already," Lowry tweeted on Sunday after the bash. "Everything worked out & I had everyone (almost) I love in the same room! Thank you all!"
Interestingly, not one of Lowry's Teen Mom co-stars was present at the wedding -- but MTV was there and cameras were rolling.
"Kail was so happy that she got to have the wedding," the insider added.
"They almost had to cancel it in the spring because of money issues, but when she signed season five of Teen Mom she was able to use that money to help fund the wedding."
