“Teen Mom 2” star Leah Messer has an ever-growing family. The MTV reality star will welcome a baby into her life, but she’s not the one who’s pregnant. Her kid sister, Victoria Jones, is expecting her first child with her husband Brian, Radar Online wrote in an exclusive report Friday.

The 21-year-old Victoria took to Facebook to share the happy news with her husband and mother, Dawn Spears. “Looks like I’m gonna be a mommy! I’ve waited so long for this and I’m glad I get to share this with my husband,” Messer’s sister wrote in a Facebook post.

A week earlier, Jones teased about the pregnancy online. “Things are going so well with our cute little home, we couldn't be happier!!” she wrote.

Jones, who married her husband in April, then shared two pictures of her at-home pregnancy test. “Jones Baby in the oven,” she captioned the photos.

Messer, 23, didn’t publicly congratulate her sister, but she did talk about potential baby names with her. When Jones talked about naming the unborn child “Adrianna Jean Jones or Joshua Eugene Jones,” Messer chimed in. “Stop it you have plenty of time to name this kid,” the reality star wrote. “HUSH,” added their mother, Spears.

Jones has appeared on “Teen Mom 2” more often in Season 6 since Messer went to rehab for anxiety and depression. On the show, she refers to the center as “treatment” and never calls it rehab. Despite Messer saying she needed to get away to deal with her emotions, her ex-husbands, Corey Simms and Jeremy Calvert, say she had an addiction to prescription painkillers. Messer has vehemently denied being addicted to drugs and passed a drug test earlier in the season. She even claimed the painkiller rumors were a story line scripted by MTV. 

“Teen Mom 2” airs on Thursdays on MTV at 10 p.m. EDT.
