The show got rave reviews from Bey's mom, who shared photos of her daughter backstage with the dancers and her mentees.

"Backstage after the Alvin Ailey dancers performance it was magnificent," Tina wrote on Instagram. "With my beautiful Tina's Angels and with a few of the mentors. My very gracious daughter who met the girls and spent some time with them and made their day!"
The "Formation" singer hid her twin-baby bump under the drapes of a large blush-colored trench coat as she surprised the dancers backstage.
