Kailyn Lowry flaunted her baby bump Monday night on "Teen Mom 2's" aftershow.
"Catch us LIVE tonight after the all new episode of #teenmom2 tonight @leahdawn92mtv," she captioned a photo on Instagram of herself with Messer.
Lowry later denied her unborn baby's father is named Larry, tweeting, "Omg you guys Larry is a producer."
The "Teen Mom 2" star had mentioned a "Larry" on the aftershow while discussing sons Isaac and Lincoln's reactions to her pregnancy.
"[They're] excited," the star said of her kids. "But they keep fighting over whether it's a girl or a boy.""Isaac is a pretty damn good kid. Larry and I talked about him babysitting -- Isaac babysitting, I mean," she added before qualifying, "Just kidding!"
Lowry had confirmed in a blog post 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 wrote at the time.
"Of course, I was filmed on the show saying I didn't want any more kids but I'm pregnant again," she said.
"When I started thinking long and hard, I knew I wanted more. This was the choice I made."
Lowry came to fame on the MTV series "16 and Pregnant" before starring on "Teen Mom 2."
The series co-stars Messer, Jenelle Evans and Chelsea Houska, and airs Mondays at 9 p.m. ET.
