Teen Mom's Kailyn Lowry has confirmed that she is expecting her fourth child.

The 27-year-old took to Instagram on Tuesday to confirm the happy news, alongside a photo of herself with her three eldest children. "We’re confirming the news, baby #4 is coming soon! I’m almost 16 weeks pregnant & it’s been a rough few months this time around," she said. “I've had nausea, morning sickness, and absolutely no energy. This week I’m starting to feel a bit better and I'm really hoping it stays this way!” She partnered with the app Peanut for the announcement. “Going through nausea and morning sickness while trying to keep the news a secret can be quite isolating. There are so many helpful threads on the app from other women who have been through it too. It's always reassuring to know you're not alone," she continued. She encouraged her followers to join the app, whether they are "already a mom, pregnant, or trying to conceive." "It's an amazing space to build friendships, find support and learn from other women at a similar stage in life. There's nothing like support from other women to get you through," she continued. Us Weekly report that the baby's father is Kailyn's on-again-off-again boyfriend, Chris Lopez. The couple have a two-year-old son together, Lux. Kailyn is also mum to 9-year-old Isaac and 6-year-old Lincoln.
