Along with dad Jay Z, the five-year-old is expected to be in the delivery room to witness the "magical family moment" — watch the video below for the details!
To make her feel even more special on the big day, the couple also reportedly splurged on a nurse's costume for Blue worth $1,015 and designed by Givenchy.
The Grammy winner is already busy preparing for the arrival of her twins.
Along with shelling out $500,000 on an over-the-top nursery for her double bundle of joy, sources revealed exclusively to Life & Style that the "Lemonade" singer has hired double the staff she had to help with Blue.
The master suite-sized nursery inside their LA home will feature "its own kitchen, fireplace, and movie theater," along with an adjoining suite for a nurse and a separate room for a nanny.
"The twins will have matching cribs and rockers and designer sheets totaling $30,000, plus a $50,000 state-of-the-art sound system," the insider detailed.

As expected, Beyoncé and Jay Z's kids will also be trendsetters at a very early age.
"The twins have their own custom walk-in closet," the source added, "and it's filled with the best designer baby clothes money can buy."
Beyoncé opened up about her struggles with infertility with Oprah Winfrey in 2013, admitting the couple had a miscarriage before the arrival of Blue.
“I felt like there were so many couples who go through that, and it was a big part of my story,” she said. "I envisioned what my child would look like... it was the saddest thing I’ve ever been through."
Today, the power couple is counting down the days until they are a family of five.
"We would like to share our love and happiness," she wrote on Instagram. "We have been blessed two times over. We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes."
