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).
8. Ryan and Rodney Jr.
Holly Robinson Peete and Rodney Peete gave their daughter a unisex name that's more common for boys, Ryan, and honored dad Rodney with their son's name.
9. Hartley and Lydon
For Sugar Ray front man Mark McGrath and his longtime love, Carin Kingsland, two unisex names were the right choice: Their daughter was named Hartley, an English name that means "deer meadow"; their son received the rocking Lydon, likely after Sex Pistols front man Johnny Lydon.
10. Zoe and Thomas
Dennis Quaid and Kimberly Buffington chose two popular names for their twins -- #31 name, Zoe, and #63 name, Thomas, on the Social Security Administration's list.
11. Harper and Gideon
For their daughter and son, Neil Patrick Harris and David Burtka picked Harper, a top 50 moniker in the U.S. that is the name of To Kill a Mockingbird author Harper Lee, and Gideon, a top 500 baby name with Hebrew roots.
12. Olivia and Malcolm
Actor Denzel Washington and his wife, Pauletta Pearson, picked Olivia for their daughter, long before the name hit the top 10, and Malcolm, which has stayed in the top 500 for the past decade.
13. Olivia and Anton
Al Pacino and Beverly D'Angelo picked two names with Mediterranean flair for their twins: Olivia, the Latin word for "olive tree," and Anton, a variant of Anthony, which means "priceless."
14. Adalynn and Noah
Former American Idol contestant Chris Daughtry and his wife, Deanna Robertson, picked Adalynn, a variant of Adeline, along with the Old Testament favorite, Noah.
