The Teen Mom 2 stars brought together their respective children to celebrate the fourth birthday of Marroquin’s son, Lincoln, in Delaware. DeJesus and her two daughters, 6-year-old Nova and 4-month-old daughter Stella, were visiting from their home in Florida.
Marroquin shares Lincoln with ex-wife and fellow MTV star Kailyn Lowry, while DeJesus shares Nova with ex-boyfriend Devoin Austin, and Stella with ex-boyfriend Luis Hernandez.
Both shared photos of Lincoln’s Power Rangers-themed birthday party on Instagram, with Marroquin writing a heartfelt thank you to DeJesus in the caption of a photo of the combined families.
“Thank you friends and family that came and made Lincoln’s birthday extremely special. Huge thank you to my girl @_brianadejesus helping me put this together and thank you @miss_teenyfabsmama for these awesome shirts. Linc loved them,” he wrote in the caption.
Marroquin and DeJesus then attended a Golden State Warriors basketball game on Saturday, with DeJesus writing on Twitter, “Warriors game tonight with bae.”
She documented the entire trip, sharing a photo of herself making s’mores with Nova in Dover, Delaware, and of her excited daughters in the Philadelphia airport while traveling to see Marroquin.
Marroquin told PEOPLE in October that he was dating DeJesus, saying they had both “decided to make it official” after the reality show reunited them for the Teen Mom 2 reunion taping in Los Angeles.
“We are dating,” Marroquin said. “We’ve been friends for a while and we weren’t in a rush.” DeJesus and MTV did not respond to PEOPLE’s request for comment.
The two have frequently posted about each other on social media, with Marroquin flying to Florida with his son Lincoln and his former stepson, Isaac (from Lowry’s previous relationship to Jo Rivera), to spend time with DeJesus, her daughters and her sister 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.”
