Leah Messer's Daughter Admits 'Teen Mom' Is Expecting Fourth Child

Kailyn Lowry may not be the only Teen Mom 2 star expecting a baby! Leah Messer's daughter revealed the mother-of-three is expecting her fourth child during a live Facebook video.

In the now-deleted video, 4-year-old Adalynn whispers to Messer, "Tell them about the baby in your belly!" A shocked Messer responded, "hold on" before shutting the video off.

But is Messer, 25, really expecting her fourth child? She denied her daughter's confession over Twitter.

"Kids say the craziest things! Side note: You have to be sexually active to get preg," she tweeted, adding, "I am definitely not. I have the IUD."

She then wrote on her Facebook page: "I am in an amazing place in my life & I have enough respect for all of you to tell you if I am pregnant! Let's just say that you have to be in a serious relationship and intimate with someone for that to happen. The only male I'm cuddling is my brand new adorable male puppy! Adalynn most definitely has a boisterous & creative personality. I was mortified to say the least, but that's a little one for ya! Thank you for all the interests tho."

Messer shares twin daughters Ali and Aleeah, 7, with ex-husband Corey Simms and daughter Adalynn, 4, with ex-husband Jeremy Calvert.

The pregnancy drama comes only days after RadarOnline.com exclusively broke the news that Lowry is expecting a child with her third baby daddy.

"I am pregnant," she confirmed on her personal blog. "Please know that 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."
