May 3 (UPI) -- Kailyn Lowry went public with baby No. 3's father this week.
The 25-year-old Teen Mom 2 star confirmed Tuesday that Chris Lopez fathered her unborn child after announcing her pregnancy in February.
"Ancestry DNA & yeah he is... stop with the headlines already," she tweeted in response to a headline reading, "Pregnant Kailyn Lowry takes DNA test -- Is Chris Lopez REALLY the baby daddy?"
"I think I'm most worried about the changes ahead but also that I will have this baby 24/7 by myself with no help. I'm going to be a single parent from the beginning!" she wrote.
Lowry already shares 7-year-old son Isaac with ex-boyfriend Jo Rivera and 3-year-old son Lincoln with ex-husband Javi Marroquin. She announced on her website Feb. 24 that she's expecting another baby in the summer.
"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," the star said.
"Of course, I was filmed on the show saying I didn't want any more kids but I'm pregnant again," she acknowledged. "When I started thinking long and hard, and I knew I wanted more. This was the choice I made."
