Teen Mom Leah Messer flaunts giant engagement ring in new video after boyfriend Jaylan Mobley proposes to star on beach

TEEN Mom Leah Messer is flaunting her giant engagement ring in a new video after she got engaged to her boyfriend Jaylan Mobley.

Jaylan, 25, proposed to Leah, 30, in a romantic beach proposal while the couple was vacationing in Costa Rica.

Leah took to Instagram to show off her sparkly diamond ring.

The ring was thicker than her finger and the jewel glistened in Leah’s closeup video.

The Teen Mom 2 star tilted her hand and held it against her legs as she lounged on her bedsheets.

She captioned her clip: “I’m obsessed.”

Leah tagged her new fiancé Jaylan in the video and also re-posted her engagement photos on her Instagram Story.

At the beach, Jaylan proposed to her with a 4.7-carat custom ring, which had been designed by jeweler Mike Nekta of New York Diamond Jewelry.

As they celebrated their first year anniversary, the MTV notable told PEOPLE: “It feels amazing.

“I never imagined myself being here today, but I couldn’t imagine myself being anywhere else.”

Jaylan added: “I can’t even express how I’m feeling.

“I wanted this moment to be the perfect moment for her.”

The mom-of-three claimed that she “knew something was going on” as they enjoyed their dinner meal prepared by a private chef.

Leah claimed to have “had no idea it was going to be like this.”

About a year ago, Leah met her partner at a concert with friends.

As their romance escalated, Jaylan bought a $500,000 home in April for the two and her children to move into.

THE BIG CLUE?

Fans suspected that Leah was engaged when she recently uploaded a dance video featuring two of her daughters: Aleeah, 12, and Addie, seven.

While in the kitchen, Leah and her kids showed off their dance moves to Demi Lovato’s song, Cool For The Summer.

Jaylan appeared in the background while the others danced.

When the spicy lyrics started, he rushed forward and yanked the camera away.

Jaylan shook his head in disapproval and wagged his finger.

The TV personality captioned the post with a laughing emoji.

Followers seemed distracted by the fancy jewelry the TV mom had on ring finger.

They congratulated the couple on their engagement even though she had not yet made an official announcement.

One fan said: “Do I see a ring on ‘that’ finger?!?!”

Another agreed and added: “I came searching the comments to see if anyone else noticed that.”

A third mentioned: “Watched a few times! Looks like she’s married! I see a wedding band and diamond.”

A fourth person wrote: “Is that an engagement ring?”

A commentator cheered: “I’m so happy for you, Leah! Congrats! You deserve a good man and to be a happy, nice-looking family!”

Leah shares twins Ali and Aleeah, with ex-husband Corey Simms and her youngest Addie with second spouse Jeremy Calvert.
