Jagger is a swaggering Rolling Stone of a name that's been picked up by a number of fellow celebs, including Lindsay Davenport and Brett Scallions--while Soleil Moon Frye pulled a gender switch when she bestowed it on her daughter. It's edgy with a touch of danger.

Jagger, made famous as the surname of Rolling Stone Mick, gets an entry in the girls' column thanks to Ashlee Simpson and Evan Ross, who chose it for their daughter. For either gender, this name rocks...but a bit jaggedly. Currently, there are nearly 20 times as many baby boys than girls are given the name Jagger. That balance may shift, making Jagger a more truly gender neutral name.
