Blake Lively welcomed her baby daughter, James, into the world last December with husband Ryan Reynolds. 

Now, she has finally revealed why she gave her daughter a boys name while doing an interview with Good Morning America.

She said, "It's a family name and I liked having a boy's name, so I thought i'd pass it on." 

She also shared a piece of advice she has for her daughter while she grows up "Don't let anyone tell you no."
