Now, it’s official: “Teen Mom” star Catelynn Lowell is pregnant. She and longtime boyfriend Tyler Baltierra gave their daughter Carly up for adoption on “16 and Pregnant.” And when news broke that the two, both 21, were expecting another child, fans were shocked. Though they did not deny the pregnancy, they never address it until Wednesday.

She took to Instagram to share the news: “#it'sofficial #4months @tylerbaltierramtv,” she captioned the black and white image, holding her burgeoning baby bump.

Hours after the photo was on Instagram, it garnered over 50,000 likes from her 400,000 followers. Hundreds of fans wished her congratulations on the image.

Lowell’s mother, April Stotts, confirmed her daughter was pregnant with her second baby in May to Us Weekly. "She was crying when she knew for sure and so I was like, 'Are you happy? Are you upset?' And she was like I’m happy!,'" Stotts told the news site. “She’s keeping the baby.”

It apparently was the couple's plan to get pregnant with another child all along. “I would’ve felt guilty if I got pregnant again when Carly was 1 or 2,” Lowell revealed to In Touch Weekly. “But we’ve both been yearning for this.”

Lowell and Baltierra were engaged, yet called the engagement off when they appeared on season 3 of VH1’s “Couple Therapy.” Though it appears the couple will go through with their nuptials after Lowell posted an Instagram picture that showed off her wedding ring.
