Lowell told the magazine. "When we did our gender reveal, I was so shocked I almost cried because I wanted a boy so badly. I'm super excited it's a girl now." Lowell and Baltierra are parents to 3-year-old daughter Novalee. The couple placed their elder daughter, Carly, for adoption shortly after her birth in 2009. "We definitely want to have a boy, but if God only wants us to have girls, then that's just what it is," Lowell said. "It will be a houseful of ALL girls! Poor Tyler!" Lowell and Baltierra had teased the news with a photo featuring Novalee on Wednesday. The picture shows the toddler holding up a sign reading, "I am such a pretty little girl my mommy & daddy wanted another one to be their world." "Excited to have Nova announce our SHOCKING GENDER REVEAL," Lowell captioned the post on Instagram. RELATED LINK: 'MARRIED AT FIRST SIGHT' COUPLES NOW: WHO'S STILL TOGETHER? WHO BROKE UP?
