Lisa Marie Presley is a mom again.

The 40-year-old singer gave birth Tuesday to twin girls by Caesarean section, according to a publicist.

The "babies and mom are happy and healthy and resting at home," according to a statement released Saturday.

The publicist, without elaborating, said the births happened on the West Coast. Presley, who is the daughter of Elvis Presley and is married to music producer Michael Lockwood, lives in the Los Angeles area.

One baby weighed 5 pounds and 15 ounces, and the other came in at 5 pounds and 2 ounces, according to the publicist.

Lisa Marie Presley has a 19-year-old daughter and a 15-year-old son by a previous marriage.
