In the weeks leading up to the birth of their babies, In Touch magazine has learned that Beyoncé and Jay Z have a military-like plan in place to make sure they get to LA’s Cedars-Sinai Medical Center without any issues.

Bey and Jay, who are already parents to Blue Ivy, 5, didn’t want LA’s notorious traffic to cause any delays when Beyoncé was ready to deliver their twins. “Their security team conducted weekly trial runs to the hospital during various times of the day,” says an insider.

“They were so nervous about getting to the hospital on time that they even considered taking a helicopter, but Beyoncé decided against it because she wasn’t comfortable with the idea,” the insider tells In Touch.

“She was happy just driving to the hospital with military precision,” the insider adds.
