It's baby girls for the happy mom!

ET confirms that Lisa Marie Presley and hubby Michael Lockwood welcomed twin baby girls on Tuesday, Oct. 7. The bundles of joy are the couple's first children together.

Lisa Marie gave birth by C-section at 2:46pm. The babies weighed 5 pounds, 15 ounces and 5 pounds, 2 ounces. The newborns and mom are happy and healthy and resting at home.

This August, ET broke the news that Lisa Marie, 40, and Michael, 47, were expecting twins. Earlier in March, when news of the pregnancy broke, Priscilla Presley told us she was "ecstatic" at the prospect of becoming a grandmother again.

As it turns out, twins run in the Presley family. Lisa Marie's legendary dad, Elvis, was a twin, and her mom Priscilla has younger brothers who are twins.

Lisa Marie also has two children with ex-husband Danny Keough.
