The two sisters who are also twins are pregnant at the same time and are due only two weeks apart from one and another. Brie was also recorded as saying, "People are going to think that's a joke. We both are shocked. People are going to think we planned it, but you can't really plan pregnancy!"

Nikki also said, "It was a total surprise. It took even me a good week to come to terms with like, 'Oh my gosh, I'm pregnant. I'm not ready for it."
