Kail’s new addition will come on the heels of two other Teen Mom 2 pregnancies. Chelsea recently welcomed a baby with husband Cole DeBoer, and shortly after Jenelle Evnas gave birth to a baby girl with fiancé David Eason.

Even though Kail confirmed her pregnancy, she has yet to announce who fathered the child, though we know the child does not belong to Javi. The 24-year-old’s love life has been a mystery lately, and fans are linking the expectant mother to two men: Tyler Hill and JC Cueva.

Fans gathered that Kailyn was in a new relationship from a cryptic Instagram post that featured a picture of a dozen roses from a secret “Valentine.” And since Javi accused his ex of cheating during his deployment, her hidden relationship might have been going on for some time.

We guess it’s only a matter of time until the reality star has to come clean about her new baby’s father!
