The 'Love On Top' singer went on to discuss the birth of Blue Ivy last year, describing it as the "best day" of her life so far.
"I felt very maternal around eight months and I thought I couldn't become any more until I saw the baby," Beyonce recalled ."But it happened during my labour because I had a very strong connection with my child.
"I felt like when I was having contractions I envisioned my child pushing through a very heavy door.
"And I imagined this tiny infant doing all the work, so I couldn't think about my own pain," Beyonce explained. "We were talking. I know it sounds crazy, but I felt a communication.
"My family and my closest people were there when I gave birth," she added. "Everything that scared me just was not present in that room. It was the best day of my life."
