According to Radar Online, Kailyn welcomed the newborn, weighing 7lbs and 15oz., at 3 a.m. on August 4. She has yet to reveal her son’s name, but she shared the exciting news on Twitter, writing, “Mother of boys.”

This is Kail’s first child with her ex-boyfriend Chris Lopez, who she split with before the baby arrived. It was previously revealed that he would not have much to do with the baby’s life and the blonde beauty was gearing up to raise this baby as a single mother.

“Things ended pretty badly with Chris so [he and Kailyn Lowry are] not even talking right now. He’s been a real a– to her, and has made it clear he doesn’t want anything to do with the baby,” a source previously told Hollywood Life. “Kailyn’s hoping he will change his mind when the baby arrives. She doesn’t care about the financial side of things, as she’s more than capable of supporting her kids herself, but she would love for him to be part of his child’s life.”

The reality star already shares a seven-year-old son, Isaac, with her ex-boyfriend Jo Rivera and a three-year-old son, Lincoln, with her ex-husband, Javi Marroquin. She first announced her pregnancy back in February with a shocking announcement on her personal website.

“I am pregnant. 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. I wanted this to be a private time so I could be excited while not getting chased by paparazzi and bothered with crazy headlines. 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 said at the time.

“Of course, I was filmed on the show saying I didn’t want any more kids but I’m pregnant again. I know so many will have comments on this but here’s the thing — I didn’t want to bring another child into a failing marriage.”
