Lisa Marie Presley welcomed twin baby girls Tuesday, according to The Associated Press.
Her publicist says the 40 year-old singer gave birth to the girls–one weighing 5 pounds, 15 ounces and the other 5 pounds, 2 ounces–by Caesarean section. The names were not yet released.
In a statement, the publicist says “babies and mom are happy and healthy and resting at home.”
Presley is married to music producer Michael Lockwood and has a 19-year-old daughter and a 15-year-old son by a previous marriage.
