"We have found out that we are going to be having a … drumroll please … another girl!" Lowell told Celebuzz at the time.

Catelynn Baltierra/Instagram While speaking with PEOPLE last October, Lowell shared her family has a "whole movie theme" going on when it comes to names. "Novalee, her name came from a movie. And Vaeda's name is from a movie as well, My Girl. And then one time we were watching the new Disney movie with our girls, Raya and the Last Dragon, and I was telling Tyler, 'Wow, isn't that a really pretty name? Like Raya is a super pretty name,' " she recalled. "So with the whole movie theme that we kind of have going on, we were like, 'Oh my gosh,' like we really ended up falling in love with the name Raya," she explained. As for Rya's middle name, Rose, Lowell said her daughter Nova was in charge of picking the second moniker. "She got to give her sister her middle name, which she was all excited about. And then we were just like, 'Cool. Rya Rose, it's really pretty,' " she said.
