"Teen Mom 2" star Kailyn Lowry confirmed her pregnancy Thursday but did not reveal who the father was. Fans speculated that the father might be either JC Cueva or Tyler Hill.

"I am about halfway through the pregnancy," the reality star said. "I know this isn't the ideal situation but those close to me have been very supportive and understanding."

The news of the pregnancy comes not long after she finalized her divorce with Javi Marroquin, with whom she has a 3-year-old son Lincoln. Lowry is also mother to Isaac, 7, whom she shares with her ex Jo Rivera. Last month, Marroquin responded to fans on Twitter after he accused his ex-wife Lowry of cheating on him.

Marroquin's accusation came after fans sent screenshots of a text message received by Lowry from a man named Tyler while she was FaceTiming with her estranged husband.

“I found out a lot of things while I was overseas that was a deal breaker. It was too much damage that can’t be undone,” Marroquin allegedly replied to the fans, according to In Touch Weekly.

There also have been rumors about a relationship between Lowry and Cueva, but the reality TV star denied the dating rumors.

“I think I have a really good relationship with Kail,” Cueva said in December talking about his closeness with Lowry. “I was a new person coming in; her previous field producer had been with her for years and years. I had big shoes to fill, but I think I did a good job. I joke around with her a lot. She likes me as a person, but she hates that I have to be a producer sometimes. We get along really great, and I think she respects me.”

Lowry had earlier said that she did not want more than two children, but later changed her mind. When asked by a fan in January if she would consider having another baby if she “met someone else and fell in love,” Lowry replied, “I think so...”

The 24-year-old also took to her website late Thursday to share a photo of her sonogram and talk about some health issues.

"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," she wrote. "I didn’t want to announce just to have another miscarriage and suffer through another grief."
