Lisa Marie Presley has named her newborn twin daughters Finley and Harper.

A publicist for the 40-year-old singer confirmed the names Tuesday, a week after Presley, who lives in the Los Angeles area, gave birth by Caesarean section.

Presley is the daughter of Elvis Presley and is married to music producer Michael Lockwood. She has a 19-year-old daughter, Riley, and a 15-year-old son, Benjamin, from her marriage to musician Danny Keough.

She married Lockwood in January 2006.
