Isaac and Lincoln are about to be big brothers now that Teen Mom 2 Star Kailyn Lowry has confirmed she is pregnant with baby number 3.

Lowry confirmed the news in a post on her website Thursday, after rumors started to swirl about the pregnancy.

"I am pregnant," she wrote. I'm sad that I should have known that people in my life would sell me out before I was ready. Like any normal person, I want it to be a happy time... Please know this was a choice I made, I already know some won't agree but I've been showered with support by the ones I love since I found out."

She also addressed why she initially waited to reveal the news, discussing her past miscarriage and revealing she didn't want to go public if there was a risk of it happening again.

"Why did I wait? I've had a lot of health complications leading up to this pregnancy and I was not ready to release such private information on my own just yet being that I am so high risk with this pregnancy. I didn't want to announce just to have another miscarriage and suffer through another grief.," she wrote.

Lowry, who said she doesn't know yet if she's having a boy or a girl, also addressed how she told Jo Rivera, Isaac's father, admitting he knew, but saying she didn't have a chance to tell ex-husband Javi Marroquin, Lincoln's father, before she announced.

However, Marroquin has now spoken out about the news on social media, telling fans on Twitter that he wouldn't give them any info on the pregnancy or reveal if he was the father, though some speculated that he was, hence his reluctance to talk about it.

However, there has been some other speculation that the baby belongs to a man Lowry allegedly cheated on him with, with Radar Online quoting sources who say the father is the man Marroquin caught in Lowry's home earlier this season.

Lowry is not the only one from the Teen Mom franchise to be welcoming another child into her life. OG star Maci Bookout welcomed her third child with now husband Taylor McKinney last spring. The couple co-parent Maci's son Bentley with ex Ryan Edwards, and are the parents of a daughter, Jayde and son, Maverick.

From Lowry's own cast, Chelsea Houska just welcomed second child Watson Cole with her new husband Cole DeBoer this January, and shares custody of her daughter Aubree with ex Adam Lind. Janelle Evans also welcomed her third child this year with new fiance David Eason, a daughter Ensley. She shares custody of second son Kaiser with ex Nathan Griffith, and her mother still has custody of her first son, Jace.
