Teen Mom's Catelynn Lowell reveals she's pregnant with her third child

Congratulations!

A huge congrats is in order for Catelynn Lowell and her partner Tyler - they're expecting a baby.

The Teen Mom star announced the news on the TV show, which airs tonight, however a special promo of the moment was shared on social media today.

In the clip, the couple's daughter Novalee Reign arrived into a room where Tyler was sitting, wearing a t-shirt that says "I'm going to be a big sister."

Tyler asked, "Why do we have that shirt?", to which Catelynn said, "Because she's going to be a big sister!"

Cue the crying and emotional hugs! The whole family is so happy!

Later in the clip, Tyler asks, "How many did you take?" before Catelynn admitted to taking four pregnancy tests.

"Oh my gosh! You're a fertile myrtle," he joked.

The moment was caught by the MTV cameramen while they were filming for the latest season of Teen Mom OG. The episode was filmed last October, as throughout the episode, the moms are all doing Halloween activities with their kids, including visiting local pumpkin patches.

Earlier this month, Catelynn checked herself into a treatment facility for unknown reasons, and after she completes a six week programme, she plans to be straight back home with her family.
