Belly rub! Kailyn Lowry cradled her pregnant Teen Mom 2 costar Chelsea Houska’s growing baby bump in between tapings for an “Unseen Moments” episode as well as an upcoming “Ask the Moms Special” this past weekend.

Houska, 25, took to Instagram to share a photo of the sweet moment. In the pic, the second-time mom-to-be — who is expecting a baby boy with husband Cole DeBoer in February — looks down as Lowry’s hands are placed on her tummy. “Loverrr,” she captioned the snap.

In a subsequent post, Houska, who is already mom of daughter Aubree, 7, with ex Adam Lind, uploaded a GIF in which Lowry is enthusiastically feeling her baby bump again.

As previously reported, Houska and DeBoer, who tied the knot in an intimate Saturday, October 1, wedding ceremony in their native South Dakota, revealed the sex of their first child together via social media on Sunday, November 6.

"It's aaaaaaa..... BOY! Can't wait to add a little man to our crazy crew!” the 16 & Pregnant alum wrote alongside a snap of herself and DeBoer, with a mini-clothesline of baby boys' clothing attached from it, as Aubree clings onto her expectant mom's belly.

Houska and the fitness enthusiast started dating in August 2014 and got engaged in November 2015. They announced in July that they were expanding their family.

"We are beyond excited for this journey and can't wait to share it with you all!" the MTV personality captioned an Instagram photo at the time. "Big sister Aubree is also extremely excited and it's no secret that she is hoping for a girl haha."
