As many fans know, Sept. 4 is a national holiday. Yes, it is Labor Day. But it's also the day we celebrate Beyoncé Giselle Knowles-Carter’s birthday. The R&B superstar turned 36 years old today and the Beyhive came out in force to celebrate their queen’s B-Day.

Fans on Twitter have begun the hashtag campaign #BeyDay to honor the R&B mom and wish her a joyous birthday. Even British singer Adele sent birthday wishes to Beyoncé. “Happy Birthday to the Queen [Beyonce]. We love you like no other x,” she wrote.

One Twitter fan summed up Beyonce's B-Day celebration perfectly. "36 years ago today, a legend was born. Happy birthday to the greatest entertainer of our generation!" she tweeted.

However, the best birthday tribute goes to Beyonce's mother, Tina Knowles-Lawson. Mama Tina went on her Instagram page and shared a sweet birthday salute to her beloved daughter. She wrote in part, "36 years ago God Chose me out of all the women in the world to be your mother! How blessed could [I] be? I am proud to be your mom. Happy Birthday Baby! I love you with my whole heart."

Happy 36th Birthday, Beyonce!
