Beyonce Gives Surprise Performance at Blue Ivy's Elementary School Gala

By
Proving she has just as much school spirit as any mom, Beyoncé gave a surprise performance at Blue Ivy's elementary school fundraiser in Los Angeles over the weekend.
As with most things Beyoncé, the performance was a tightly kept secret beforehand. "About 20 minutes before she went on stage there were rumors that Beyoncé would be performing -- but no one was 100-percent certain until she actually walked out," an eyewitness exclusively told ET. The source added that while it was a short set, the singer had everyone on their feet and dancing "the moment she started singing."
The "Formation" singer appeared on stage in a sparkling black and gold mini-dress to sing a few of her hits -- including "Crazy in Love" -- and a cover of Whitney Houston's version of "I Will Always Love You" for attendees at the school's 75th anniversary gala.
Attendees, predictably, went wild.

"Just another mother at school helping out at the annual fundraiser," one attendee noted in the understatement of the year. 

Blue Ivy is just 4 years old but attends the Los Angeles-area school, which bills itself as "a socio-economically and culturally diverse independent school for children, toddlers through grade six, [that] strives to graduate students who are joyful, resilient, life-long learners."
Beyoncé recently posted adorable photos of Blue Ivy with Chris Martin during the Super Bowl halftime show rehearsals. Check out more in the video below.
