Beyoncé is opening up about the difficult pregnancy with her twins, Sir and Rumi, whom she gave birth to in 2017. In her new Netflix special, Homecoming: A Film by Beyoncé, she got extremely candid.

“I was supposed to do Coachella the year prior, but I got pregnant unexpectedly,” she reflects. “It ended up being twins, which was even more of a surprise. My body went through more than I knew it could.”

The singer said she was 218 pounds when she gave birth to the twins.

“I had an extremely difficult pregnancy,” she continued. “I had high blood pressure. I developed toxemia, preeclampsia. And in the womb, one of my babies’ heartbeat paused a few times, so I had to get an emergency C-section.”
