The moment we've been waiting for has finally arrived. Hot off the heels of announcing plans to expand her family, Teen Mom's Catelynn Lowell is reportedly four weeks pregnant with her second child. Hip-hip-hooray!

While Catelynn and her fiance, Tyler Baltierra, haven't addressed the news — they'll likely wait to speak out about the pregnancy until Cate reaches the 12 week mark —  two of their family members took it to Facebook and blabbed.

According to The Ashley's Reality Roundup and Starcasm, Catelynn's brother, River, tagged Catelynn's official Facebook page and posted "Catelynn is pregnant." Meanwhile, mom April wrote "Gonna be a grandma again." April also added that Catelynn is around 4 weeks pregnant, while River noted that he thought she was due January 10. Meanwhile, Tyler himself commented on April's post, saying "Love you momma!”

This is great news for Catelynn and Tyler, who have made it clear that they're more than ready to become parents — despite the fact that they placed their first child, Carly, up for adoption when they were teenagers. "We’re trying to have a baby,” Cate and Ty confirmed to In Touch. “I would’ve felt guilty if I got pregnant again when Carly was 1 or 2. But we’ve both been yearning for this… We’re ready to have a baby!”

Are you excited to hear the reports of Catelynn's pregnancy? We have a feeling she and Tyler are going to be amazing parents, so take it to Twitter and wish them well!
