James is the hottest name for celebrity parents this year. Mila Kunis and Ashton Kutcher may have started the gender-twisting name trend when they named their daughter Wyatt, however the popularity of boy names for girls really caught steam when Blake Lively and Ryan Reynolds named their daughter James.
Since then, the gender-bending name trend is showing no signs of slowing down. In addition to Martin choosing the middle name of James for her daughter, Kristin Cavallari named her daughter Saylor James, Jennifer Love Hewitt named her daughter Autumn James, and model Coco Rocha named her daughter Ioni James.
The ER alum balanced out her daughter’s masculine middle name with the feminine name of Olivia, which is a Spanish name meaning "olive." According to the Social Security Administration’s list of top baby names, Olivia is currently the second most popular girl name here in the United States, with Emma nabbing the top spot and Sophia landing in the third-place spot.
Several other celebrities have also chosen the sweet name of Olivia for their daughters, including James Van Der Beek, Eddie Vedder, Colin Hanks and Wanda Sykes.
Martin announced her pregnancy when she was five months along and had fun showing off her growing baby bump — reassuring her fans that, “Yes, there is only one baby in there,” after showing off her bump in a formfitting dress at the Hallmark Channel TCA party.
