Their son's adorable name isn't a huge surprise. In a 2010 interview with Access Hollywood, Pink explained, "My dad's name is James, and my brother's name is Jason. [Carey and I] are both Irish, Carey's middle name is Jason, and Jameson—we like whiskey. That's a no brainer."

The "Just Like Fire" singer and hubby Carey Hart also share a 5-year old daughter, Willow Sage Hart, together. Just on Christmas morning, the couple let their cute kiddo rock some very bright colored locks ahead of their second child's arrival. Hart shared a fun photo of Willow on Instagram:

Congratulations to the happy family.
