Maci Bookout announced via Instagram Sunday she is pregnant with her third child.

"#Makingmoremoneys baby boy coming soon!" the "Teen Mom OG" star said in her post, which accompanied a photo of Bookout kissing her fiance Taylor McKinney, while they both have their hands resting on her baby bump.

"Happy valentine's day! @tmon3yyy #lastbutnotleast"

Bookout, 24, and McKinney, 26, announced their engagement last month.

They welcomed a daughter named Jayde in May 2015, but did not disclose their son's anticipated due date.

Bookout also has an older child from a previous relationship.
