KAILYN Lowry has quietly changed her name on her personal Facebook account, with no explanation.

The Teen Mom recently teased some big revelations about her family, after learning some long-hidden secrets.

Earlier this week, Kailyn claimed that a major bombshell was dropped on her life, after receiving DNA test results back.

Though she hasn’t provided an official update, fans online noticed a new addition to her social media presence – Kailyn changed her full name to Kailyn Irwin Lowery.

In an online chat room, fans speculated what the 31-year-old new mom was trying to insinuate, with many wondering if she was slyly doubting her lineage, and whether Raymond Lowry was her actual dad.

Others weren’t buying it.

“Is she trying to make us all believe that he isn’t her father?” one person questioned. “I mean it’s kind of obvious considering they’re basically identical twins.”

Another agreed, “She looks EXACTLY like her father! No DNA test needed, unless he has a twin brother, like you said.”

A few die hard fans remembered that Irwin was actually the maiden name of her estranged mother, Suzi.

“Her mothers last name is Irwin. Not a stretch for her to use it,” one person noted, adding, “It isn’t the only time she has.”

Another person explained, “She (changed her last name) right before she married Javi, (but) did not make it public.

“She kept her ‘acting’ name as Lowry. Then changed it back.”

DNA TNT

On Monday, Kailyn opened up about her experience after sending a DNA test to her biological father without warning.

The reality star spoke about the decision on her Instagram Stories Monday, as she asked her 4.6 million followers for advice.

The TV personality went makeup-free and had her blonde hair styled in curls.

She wore just a tan sports bra as she addressed her fans.

“Alright guys, it’s 10:30 pm, and last week I did a story saying I was going to send my dad DNA kits to figure out what the f**k comes from his side.

“My sister and I reconnected and so we’re just trying to figure out who the f**k we are. We grew up without him, blah, blah, blah.”

Kailyn continued, “So I sent him Ancestry and 23 & Me without saying anything. I didn’t even tell him it came from me. He got it – my aunt texted me, my sister texted me, whatever, saying that he called my aunt.

“I was not prepared for the bombshell that just got dropped on me. So I’m going to process that tonight. I’m going to circle back tomorrow and update you guys on what I found out. Stay tuned,” she closed.

WELCOMING TWINS

The Teen Mom star’s difficult DNA situation comes just days after she opened up about the difficult birth of her twins and the medical procedure she endured.

Kailyn finally shared details about the intense delivery on Friday’s installment of her Barely Famous podcast with her baby daddy, Elijah Scott, 25.

During the episode, the couple recalled their twins’ traumatic birth, with Kailyn revealing they came earlier than planned.

“I ended up delivering at 35 weeks,” she said, though the young mom admitted she expected they would arrive two or three weeks earlier.

Kailyn also noted that she canceled her scheduled C-section because she wasn’t happy with the dates her doctor offered her.

She also wasn’t exactly thrilled about the idea of having a C-section and was “terrified” the entire time.

“I have a whole list of… I cried a lot. Mainly out of absolute fear of having a C-section,” the former reality star said.

“I was terrified because I didn’t love the idea, but I knew I had to do it because the baby was breached.”

To add to the scary experience, Kailyn feared that her babies weren’t breathing when they were born.

The twins were immediately taken to the NICU, and Kailyn was unable to see them for some time – a similar situation she experienced after the birth of her and Elijah’s one-year-old son, Rio.
