Yes, Beyoncé's a Mom of 3, and Wow, Blue Ivy Is Growing Up FAST!

Blue Ivy Carter was born on January 7, 2012. Despite just being a kid, she already has a seriously killer fashion sense judging by her mom's Instagram. She also plays big sister to her siblings, Sir and Rumi.

Beyoncé and JAY-Z welcomed their twins, Sir and Rumi, into the world on June 13, 2017. Although the singer has shared dozens of photos of Blue Ivy on social media, she's kept her younger children totally out of the spotlight thus far. In the documentary Homecoming, the 37-year-old mom explained that her second pregnancy was especially taxing on her body.

"I was supposed to do Coachella the year prior, but I got pregnant unexpectedly," she explained in a monologue. "And it ended up being twins, which was even more of a surprise. My body went through more than I knew it could. I was 218 pounds the day I gave birth. I had an extremely difficult pregnancy. I had high blood pressure, toxemia, preeclampsia, and, in the womb, one of my babies' heartbeats paused a few times, so I had to get an emergency C-section."
