Model Chrissy Teigen and award-winning singer John Legend welcomed their first child, a daughter named Luna Simone Stephens, on April 14, 2016. Take a look at some of the other unusual baby names chosen by celebrities over the years.
Singer Fergie and her husband, actor Josh Duhamel, named their son Axl Jack. "(The name is) kind of traditional, kind of not," Duhamel explained to People magazine, noting that his wife "is a little rock and roll, so she's a little bit more daring in that department than I am." Nevertheless, Axl Jack is "a name that we both really love, and I think will suit this child."
