A hot starbaby name – chosen by Kelly Ripa, Chris Rock, Lisa Bonet, Denise Richards and Charlie Sheen, Carnie Wilson, and Annie Lennox, and used as the nickname of Madonna's Lourdes – Lola manages to feel fun and sassy without going over the top.

Rosalie hit its apex in 1938 and then slid straight downhill until it fell off the U.S. Top 1000 completely in the 1980s, only to spring back to life in 2009 as the name of a character in the Twilight series. The beautiful vampire Rosalie Hale has breathed fresh life back into this mid-century name, and the fact that the character is both sympathetic and relatively minor means Rosalie has the chance to thrive again as a baby name without feeling unduly tied to Twilight.
 For a long time Rosalie's main claim to fame was via the eponymous 1928 Broadway musical, which became a movie ten years later, both of which included a hit song.
 Rosalie was used as a character name in literature by Anne Bronte and Oscar Wilde. In the mid-twentieth century, Rosalie was the name of the daughter on The Goldbergs. More recently, Rosalie is a character on Grimm.

 Young Disney channel favorite Selena Gomez, former star of The Wizards of Waverly Place and current pop singer, was named after Selena Quintanilla. Selina Kyle is the secret identity of Catwoman. Selena is an alternate name of Artemis, the Greek goddess of the moon and hunting.
