We already know that Kailyn Lowry is going to become a mother-of-three this summer — but is she having a girl or a boy?

The Teen Mom 2 star confirmed in February that she is expecting baby No. 3 after months of denying the rumors — and she just revealed some exciting details about her baby’s gender. When Teen Mom OG star Catelynn Lowell tweeted she “wants to make sure” the unborn child is a girl, Kail replied with, “LOL!!! I still think it’s a boy.”

While we won’t know for sure if the blonde beauty has a son or daughter until the baby arrives, this is hardly the first time she believed that she would add another son to her boy brood. The reality star shares a seven-year-old son, Isaac, with her ex-boyfriend Jo Rivera and a three-year-old son, Lincoln, with her ex-husband, Javi Marroquin. This time around, Kail’s baby daddy is her ex-boyfriend Chris Lopez.

“You guys, I had a dream the baby was born and now I’m convinced I know the gender,” she tweeted back in February — and she later tweeted that the baby was a boy in her dream!

However, most of her fans are convinced she’s having a girl this time around because of the way she’s carrying the baby.

“For sure it’s a girl,” one user commented on this photo.

Kail has also been struggling to come up with names for her new addition, though she recently admitted she likes the idea of having a last name as a first name.
