Jason Derulo Reveals Name of Baby Boy, Says Birth of Newborn Was 'Happiest Day of My Life' Since welcoming their baby boy, Derulo and Frumes have both posted several shots of their son on social media but have continued to avoid showing his face. Last week, the new mom clarified why she won't be showing her newborn's face online anytime soon. Frumes shared a comment from one of her recent posts that read, "Just don't post the dam baby if u not gonna show his face...doing the most." She wrote on top of the screenshot, "Imagine being this mad about someone not showing you what their kid looks like," adding laughing emojis. In another slide, Frumes explained, "I've been very private this entire journey which has brought me so much peace. It's MY choice to not expose my babies [sic] face online. A lot of y'all feel too entitled to voice opinions NO ONE asked for." "My baby is beautiful & 100% healthy but at this time my baby is brand new to the world I refuse to let the negative energy of social media mess with my families [sic] energy," she added. "I will show him when we feel ready. Until then keeping all this perfection to ourselves to enjoy. Thanks."
