Teen Mom star Javi Marroquin’s ex-fiancee Lauren Comeau poses in a red bikini for a rare photo with son Eli, 3

TEEN Mom star Javi Marroquin's ex-fiancee, Lauren Comeau, has posed in a red bikini while on the beach.

She posted the rare photo to Instagram as she smiled next to her son, Eli, three.

Lauren squatted down next to her son and held his hand as she wore a red bikini.

The mother/son duo smiled for the camera and she blocked the sun with black sunglasses.

The Teen Mom alum posted a series of photos where they were soaking up the sun.

Eli smiled in one after walking in the sand.

In the next few shots, he's running towards the ocean and gets further in each time, only staying by the surface of the water.

Lauren even posted a video of Eli looking at dolphins in the water and asked him, "Do you see it?"

He asked, "What is that?" as the waves rolled on top of the dolphin.

She captioned the post, "Our happy place. These are the days I will remember. These are the faces I need most. Everything changes but I'll keep forever, these days I will remember, these days I will remember."

Lauren and Javi had Eli together and she appeared on a few episodes of Teen Mom, due to being his fiancee at the time.

REUNITING

Teen Mom fans wondered if the exes got back together after they reunited during an outing with their children just last month.

The reality star shared the sweet snap on his Instagram Stories

They enjoyed a family night at the NBA finals with their boys.

The former couple smiled for the shot as their three-year-old son Eli sat on his dad's shoulders.

Javi's oldest son, Lincoln, eight, who he shares with his ex-wife, Kailyn Lowry, 30, also attended the event and posed in the photo.

Fans were shocked about the reunion as the exes haven't been on the best of terms.

"I hope she didn’t go back to this little troll. Lauren huneyyyyyyy just use him like how he used you!" one person commented.

"I don't think they are together, but this is not about co-parenting either...it's toxic and damaging, especially to those kids involved," one said.

NASTY SPLIT

The ex-couple had been on and off since 2017, splitting ways temporarily when the MTV star dated Teen Mom's Briana DeJesus, 28.

The duo reconciled in March 2018 and announced their pregnancy weeks later.

Javi and Lauren welcomed their son Eli in November of 2019, but less than a year afterward, their relationship was hit with a cheating scandal.

The mother of one caught her baby daddy naked with another woman in their Delaware home during a party with friends.

The controversial father later took to Instagram to issue a public apology, writing, “Lauren, I’m sorry for my mistakes, I’m sorry I broke your heart, I’m sorry I disrespected you. I’m sorry I took you for granted. I could say sorry for a million other things but I’m sorry will never be enough.

“I hurt the one person that I love the most. I will do everything in my power to become a better man and hopefully one day you can forgive me. I’ll do anything to have you home.”

She took him back weeks later, but they split for good when his ex-Kailyn revealed on Teen Mom 2 in 2020 that he tried to have sex with her.

The exes have not publicly commented on the outing.

Lauren still appears to be single as she has not publicly posted about a significant other on her Instagram.
