Entertainment TV Kailyn Lowry's Ex Javi Marroquin Says He's Dating 'Teen Mom 2' Star Briana DeJesus "We've been friends for a while and we weren't in a rush," Marroquin tells PEOPLE By Alexia Fernández Published on October 24, 2017 11:10 PM Share Tweet Pin Email There’s a new behind-the-scenes romance on MTV’s Teen Mom 2. Javi Marroquin tells PEOPLE that he and his costar, Briana DeJesus, “decided to make it official” after the reality show reunited them for a reunion taping over the weekend in Los Angeles. “We are dating,” Marroquin says. “We’ve been friends for a while and we weren’t in a rush.” DeJesus and MTV did not respond to a request for comment. While this is the first time Marroquin has declared them official, the pair has been hinting that a relationship was brewing between them on social media in several Instagram posts and tweets. DeJesus shared a cheeky post on Instagram Sunday of her and Marroquin and captioned the image, “Daddy Javi 😜.” She followed it up a day later with a photo of them together: “Daddy Javi p2.” https://www.instagram.com/p/BafgALjj186/?taken-by=_brianadejesus https://www.instagram.com/p/BakHirvDjE_/?taken-by=_brianadejesus Marroquin also shared two photos of the pair on Instagram. “Views 👨🏽👸🏽🌆,” he captioned a photo of duo standing side-by-side in front of a city skyline. “I have a 6 pack from laughing so hard these last couple of days #IMY#SCORPION #BAE#CHICKENFINGERS&BBQ #GAPING#BOUJEE #YOUCHANGEDINLA#PLAYTHATCARDIIIIB,” he wrote in a second post. https://www.instagram.com/p/BajzfhpnvtF/?hl=en&taken-by=javim9 https://www.instagram.com/p/Bam-J8on4yq/?hl=en&taken-by=javim9 The reality stars both have children from separate relationships. DeJesus, 23, has two daughters: 6-year-old daughter Nova with ex-boyfriend Devoin Austin, and 3-month-old daughter Stella with ex-boyfriend Luis Hernandez. Marroquin shares 3-year-old son Lincoln with ex-wife Kailyn Lowry, who also stars on Teen Mom 2. He has a close relationship with his former-stepson, Isaac, from Lowry’s previous relationship with Jo Rivera. He visited DeJesus and her sister, Brittney, in Florida in mid-September and shared a photo of the trio sitting together while out on the town. “Thank you @laurentbaud for taking care of us at @taodowntown last night,” he wrote in the caption of the photo, which captured Marroquin with his arm around DeJesus. “We all had a great time. If y’all are in the city, be sure to hit him up for connect.” https://www.instagram.com/p/BZJRtT0nQhP/?taken-by=javim9 At the end of September, Marroquin returned to Florida with sons Lincoln and Isaac, where they spent time with DeJesus, her daughters and Brittney at a water park. “Florida was full of Long days, but the kids enjoyed themselves and I got to spend time with these two sissy’s,” he wrote in the caption, referring to DeJesus and her sister. “Surrounded by amazing people this week.” https://www.instagram.com/p/BZrT87EHXu8/?taken-by=javim9 Although Marroquin is dating his ex-wife’s costar, it seems everything is fine with Lowry. The pair — who are writing a book together titled, He Said She Said — is currently starring in Marriage Boot Camp: Reality Stars, on which Lowry broke down in tears over a simulation of Marroquin’s death in an effort to repair her relationship with her ex. https://www.instagram.com/p/BaM1qNkHSPP/?taken-by=javim9 In an Instagram post in mid-October, Marroquin shared a sweet post of himself kissing Lowry on the cheek. “Despite everything that happened between us I’m happy we are at a place where we can go to events..have a good time and be civil,” he wrote. “We’re doing a pretty good job raising these kids 🙌🏻 @kaillowry #oneteam.”
