1. Monroe and Moroccan
Mariah Carey and Nick Cannon picked this exotic, unisex set for their boy-girl pair. Monroe started out as a man's name -- it's Scottish, connected with the Roe River -- but Mariah and Nick chose it for their daughter, in honor of the iconic Marilyn Monroe. Moroccan is based on the country Morocco, and is an unusual choice for a boy.
2. Emme and Max
Jennifer Lopez and Marc Anthony opted for a nicely complementary set of baby names, with the "m" sound throughout. Emme was invented for the supermodel who bears it, similar to Emma and Emily; Max is the shortened version of the classic Maximilian.
3. Vivienne and Knox
Angelina Jolie and Brad Pitt chose diverse names for their twins. Vivienne is an ultrafeminine French name that means "life"; Knox, a Scottish surname, fits in nicely with the names of their other sons, Maddox and Pax.
4. Hazel and Phinnaeus
For Julia Roberts and Danny Moder, only old-fashioned names would do: Hazel is a nature name, from the nut tree, and Phinnaeus (nicknamed Finn), means "oracle."
5. Lucy and John
By-the-book crime reporter Nancy Grace and husband, David Linch, went super-classic with their picks, Lucy and John.
6. Coco and Sawyer
Actress Diane Farr and husband, Seung Chung, chose current celeb favorite Coco (as in Chanel) for their daughter, and Sawyer (as in Tom Sawyer) for their son.
7. Julitta and Hudson
The son and daughter of Marcia Gay Harden and Thaddaeus Scheel get a pair of unusual names -- Julitta is the Dutch variation of Julia, and Hudson is an English name that references explorer Henry Hudson (and the river that bears his name).
