Kendall and Ross Robbins said Monday they named the children Rowan Luke and Kai Leia and decorated their nursery in a "Star Wars" theme.
Their middle names are two of the main figures in the movie franchise. The couple says they chose to be induced on May 4 and had other middle names picked out just in case, but didn't need to use them.
As Kendall Robbins says, "the force is strong with them."
The twins' home nursery is decorated in a "Star Wars" theme.
The story was first reported by KSTU-TV in Salt Lake City.
