Blue Ivy Carter has already started following in her superstar parents' footsteps, and she hasn't even lost all her baby teeth yet. When it comes to choosing your child's name, there's a lot of pressure to make sure it stands out with personality, and what better way to christen the infant than with a favorite color or a number one finds lucky? Blue Ivy Carter's name may just be a combination of the two.

Her father, rapper and business mogul Shawn "Jay-Z" Carter may have something to do with his eldest daughter's first name. He has rapped about the color blue being his favorite on his track "Go Crazy," stating" My favorite hue is Jay-Z blue," not to mention his string of albums titled "The Blueprint."

However, there are other theories that suggest Beyoncé Knowles-Carter is the mastermind behind "Blue." On her official Tumblr blog, the "Single Ladies" singer posted a clip of her and Jay-Z taking a stroll past a tree in Croatia. She wrote, "We woke up this morning and took a nice little walk and passed by this beautiful blue tree. I think it's Blue Ivy, which will be quite appropriate" via Billboard. We think the color blue must be a Carter family favorite and must have influenced Blue Ivy's name.
