It's definitely been a difficult pregnancy for Beyoncé this time around, but the big day is almost here!

In Touch is exclusively reporting that Bey and her husband, Jay Z, have already made a laundry list of diva demands for LA's Cedar-Sinai Medical Center to follow then they come in to welcome their twins — but the former Destiny's Child bandmate has one major fear, that her estranged father and former manager, Mathew Knowles, will show up unannounced.

“She is fearful that he’ll show up uninvited like he did with [their five-year-old daughter] Blue. She doesn’t want him anywhere nearby on her special day. She fully expects everything to be perfect as they become a family of five,” says the insider.

Bey's mother, Tina Lawson, will be in charge of "keeping the hospital staff on their toes" that day, so we're sure it will be difficult for him to find a way in.

“She isn’t easy to get along with, and she will be even more demanding than Beyoncé. Jay knows to let her take over and stay out of her way.”

"[They] prepared an A and a B team as decoys to confuse photographers and fans, and everyone signed confidentiality agreements. Jay and Beyoncé have also been arguing with the hospital about the use of security cameras. Jay doesn’t want cameras in the room, hallways or elevators, which is an impossible request,” our source explains, adding that “they also made a plan to have everything fully catered so they don’t have to socialize in the hospital.”
