Reality TV star Maci Bookout, from MTV's "16 and Pregnant" and "Teen Mom," has announced she is pregnant with her second child.

The TV personality announced the news on social media before removing her posts.

Bookout, 23, is famous for partaking in MTV's "16 and Pregnant," which chronicled her teenage pregnancy with her first child, 6-year-old Bentley. She then starred in the spin off series "Teen Mom" that followed her as she struggled with teenage motherhood.

According to Us Weekly, Bookout broke the news on Twitter, which led to increased activity on her account. She also tweeted: "Did we break the internet?" before taking down the tweet.

"I started having very strange symptoms, like my legs were very itchy and I had tenderness in my breasts. So we got a test and it said I was pregnant," Bookout told In Touch in an interview. She also took four more tests to make sure the first was correct.

"I didn't think that another pregnancy was possible," she said, since she was diagnosed with polycystic ovary syndrome (PCOS). She believed Bentley would be her only child, as doctors said she could never conceive again.

The new baby, who does not share a father with Bentley, is expected in June.

"We still can't believe it. It was a huge shock, but we are very excited," Bookout said.

E! News reports the baby's father is Bookout's boyfriend of two years, Taylor McKinney, whom she started dating after breaking up with Bentley's father, Ryan Edwards.

"Bentley is beyond excited," she also said. "He's already nicknamed the baby Bubby."

On whether she and McKinney will get married, she said: "Before I got pregnant, we talked heavily about marriage, and we still do, but I don't wanna be a pregnant bride. That would be way too stressful. Plus, I want to be able to have fun at my wedding."
