Jennifer Lopez has '#proudmama' moment as son Max performs in school play, 'Wizard of Oz'

Jennifer Lopez and Marc Anthony's 12-year-old twins are talented, to say the least. And they've had a big month.

First, their daughter, Emme Maribel Muñiz performed with Lopez at Super Bowl LIV during the halftime show, and Friday Lopez shared a video of her son, Maximillian David Muñiz singing solo during his school's production of "The Wizard of Oz" on Instagram.

"The littlest munchkin. ♥️ #WizardOfOz #proudmama," she wrote in the caption of the video. Max, 12, played the "coroner munchkin," according to People. He sings an announcement that the Wicked Witch of the East had died. Dorothy and company cheer with excitement at the news.

And Lopez's munchkin has quite the fan base outside of Oz, it appears.

Actor Mario Lopez commented a simple smiley face ":)" and Tracy Anderson, fitness entrepreneur commented too, "INCREDIBLE!!!!!! Go Max!!!!!! ⭐️♥️."

By Saturday afternoon, the video has received nearly five million views on the social media platform.
