If the unique name sounds familiar, it is: Two celebrity babies born in 2014 share the moniker. Kourtney Kardashian and Scott Disick named their third child, a son born in December, Reign Aston, while rapper Lil' Kim gave birth to daughter Royal Reign in June.

Nova is the couple's second child. After welcoming a daughter, Carly, in 2009 when they were teenagers, the pair -- who have been together since middle school -- made the difficult decision to give her up for adoption. Their story has been chronicled on MTV's "16 and Pregnant" and "Teen Mom."

Now that Lowell and Baltierra, both 22, have chosen to bring another child into the world -- one they will raise themselves this time -- they've felt forced to defend their decision. "So sick of the ignorance in the world," Baltierra tweeted on Jan. 3. "Just because you place a child for adoption doesn't mean [you're] not allowed to have another #GetReal."
