Jenelle Evans and her boyfriend Nathan Griffith are expecting their first child together, and on next week's episode of "Teen Mom 2," Jenelle will be seen as she reveals her baby news to her family -- including son, Jace.
In a March 26 sneak peek clip posted by Wetpaint Entertainment, Jenelle is seen arriving to her mother's house, where her four-year-old son lives, and heading to his bedroom where she sits him down and reveals to him that he will soon be a big brother.
"You know what this is?" Jenelle asks as she shows her son a photo of her ultrasound. "This is a picture of a baby in mommy's tummy. Are you excited to have a little brother or a sister?"
Although Jace seems a big confused at first, he eventually warms up to the idea and appears excited to be able to teach his sibling everything he knows.
When the series' fifth season first premiered in Jan. 2014, Jenelle claimed her new pregnancy would not be shown. So, it's a bit odd to see that it definitely is shown, and will continue to be shown until the season wraps later this spring.
