Catelynn Lowell is bumpin’ along! The pregnant Teen Mom OG star shared her beautiful maternity photos taken by her husband, Tyler Baltierra, exclusively with Us Weekly and revealed the couple are both hoping for a baby boy.

“I think we both want a boy for sure, but also we have Nova,” Lowell, 26, told Us, referring to the duo’s 3-year-old daughter. “So it’s, like, if we’re just meant to have girls, we’re meant to have girls.”

Us broke the news on September 13 that Lowell is pregnant. The longtime couple, who wed in 2015, placed their eldest daughter, Carly, now 9, for adoption in 2009.

Lowell added: “With Carly too, it’s like Tyler just makes girls. The guys make the gender.”
