The singer has performed while pregnant before -- you'll remember she knocked it out of the park at the 2011 VMAs while carrying Blue Ivy -- so, we knew she'd slay.
Beyoncé was introduced by her mother, Tina Knowles-Lawson, before taking the stage and performing hits from her recent album Lemonade, which is up for Album of the Year and Best Urban Contemporary Album. Beyoncé is also nominated for Record and Song of the Year for "Formation" and Best Rock Performance with "Don't Hurt Yourself."
The performance was an epic show filled with Black girl magic.
Beyoncé, 35, surprised fans when she announced Feb. 1 that she and Jay Z, 47, would be welcoming two new additions to their family later this year.
The couple are already parents to daughter Blue Ivy, 5.
