Teen Mom star Javi Marroquin’s ex-fiance Lauren Comeau stuns & shows off her curves in a skintight dress in new photo

TEEN Mom star Javi Marroquin's ex-fiance, Lauren Comeau has shown off her curves in a new photo.

The mother-of-one stunned in a skintight dress that she showed off on Instagram.

Lauren spent the day at an amusement park with her son before cleaning up and snapping a photo of herself.

The ex-reality TV star straightened her hair, which appeared to be blowing in the wind as pieces were all over the place.

She smiled a huge smile with light pink lipstick and mascara.

The Teen Mom star wore a tan dress with white flowers on it and paired the look off with dangly earrings.

Lauren stood in front of trees, but her location was not known.

She is the ex-fiancee of MTV star, Javi, and they share one child together- a son named Eli.

The 30-year-old and her son have been traveling around the country, soaking up the sun, in different states this Summer.

This is not the first time Lauren has shown off her curves in an Instagram photo.

HOT MAMA

Earlier this week, Lauren wore a black swimsuit that showed off her curves while on vacation with her son.

The Teen Mom 2 alum shared a video flaunting her curves on her Instagram.

In , taken while the mom of one was vacationing in Vermont, Lauren and her five-year-old, sidestep onto a fallen log that had been bridged across a small pond.

Lauren rocked a curve-hugging black one-piece swimsuit as she guided her son to the middle of the log.

Captioned, "Chasing waterfalls...", the recording shows the MTV star and her son jump feet first into the watering hole below.

BEACH DAY

In early July, she posed in a tiny red bikini while on the beach with Eli.

Lauren squatted down next to her son and held his hand.

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."

ABS-OLUTELY STUNNING

In May, the mother-of-one flaunted her abs in a steamy crop top and jeans in a video she posted to her Instagram.

Lauren showed off many outfits in a reel.

It kickstarted with the former Teen Mom 2 star holding up the wardrobe in white plastic hangers. 

From floral shorts to jean shorts, the MTV alum strutted across the floor and showed off her long legs. 

She flashed a huge smile while wearing a grayish crop top, which teased her bare midriff.

Lauren displayed her backside from the cutouts on the black blouse. 

The reality star wrote in the caption: "I have a box of items size small & medium that I’m going to box up and ship out, new and unworn."

The Nicky Youre song, Sunroof, played in the background. 

Lauren lives in Delaware with her son, after splitting with Javi.

The exes recently reunited, however, when they got together with their kids for an NBA finals game.
