Pregnant Beyonce stopped by a Los Angeles performance by the Alvin Ailey American Dance Theater on Saturday to support her mother Tina Lawson and Tina’s Angels, the mentorship group founded by her mother. The Hold Up singer, who looked stunning in her dress and pink coat, made the day of some of the young dancers who were performing by surprising them backstage, reported People.com.

Lawson shared a photo on Instagram and captioned it, “Backstage after the Alvin Ailey dancers performance it was magnificent. 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!”
