Chelsea Houska has just shared a new tweet in regard to Kailyn Lowry's recently confirmed pregnancy. Less than one month after welcoming her second child, the "Teen Mom 2" star issued a congratulatory message to her co-star, who is expecting her third child later this year.

"Congrats [Kailyn Lowry] I'm so excited for you!!!" she wrote. Meanwhile, Lowry's other co-stars, Leah Messer and Jenelle Evans, have remained silent in the months since her confirmation.

That said, rumors have been swirling which have suggested that Evans actually broke the news on her own page after hearing that Lowry was pregnant from her MTV crew.

Chelsea Houska welcomed son Watson Cole last month

Chelsea Houska tied the knot with Cole DeBoer at the end of last year and on January 25, she gave birth to their first child, son Watson. As fans will recall, Houska also shares an older child, 7-year-old daughter Aubree, with her former boyfriend Adam Lind.

Since welcoming the child, Houska has been sharing updates with her fans and followers on Twitter and posting new photos of the boy on Snapchat and Instagram.

Jenelle Evans gave birth to daughter Ensley in January

One day before the birth of Chelsea Houska's son, Jenelle Evans and her boyfriend, David Eason, welcomed their first child together, a baby girl. Evans initially denied that she was pregnant last summer but after a police report blew her cover, she came clean to fans on Instagram.

Following the birth of Evans' third child (she also has two older sons, Jace, 7, from her relationship with Andrew Lewis, and Kaiser, 2, from her relationship with Nathan Griffith), Eason proposed.

Once Lowry gives birth to her third child, she will join the ranks of Jenelle Evans and Leah Messer, both of whom have three children a piece. Messer was married twice and shares 7-year-old twins with her first husband and a younger daughter with her second husband.

To see more of Chelsea Houska and Kailyn Lowry, as well as their co-stars, Leah Messer and Jenelle Evans, tune in to "Teen Mom 2" season 7B on Monday nights at 9 p.m. on MTV.
