While Queen Bey rocked sparkling one-legged pants and a midriff shirt at her celebration, her rapper husband really got into the spirit of the era with a towering wig, bandanna and military-style jacket (that made him look like rocker Jimi Hendrix) as they did a sexy version of the beloved TV show's line dance.

The singer later changed into hot pants as a cake topped with sparklers was brought out, and the couple's daughter, Blue Ivy Carter, stole the hearts of partygoers as she wished Beyoncé "Happy birthday, Mommy!"

On Sunday, September 4, the Grammy winner and her husband attended the Budweiser Made in America Festival in Philadelphia, where she was spotted chatting with former President Bill Clinton.

Before the first couple of music watched headliners Coldplay perform, Chance The Rapper sang "Happy Birthday" to his "Auntie" Yonce.

Beyoncé took to Instagram on Monday to thank everyone for the birthday wishes.

"I just want to say thank you to everyone for all the beautiful and thoughtful birthday wishes," she wrote. "I am so fortunate to have the love and support of my family, my friends, and my hive. We've grown up together and you guys continue to inspire and motivate me every day. I'm so grateful for every challenge, every smile, every tear, every discovery, every sacrifice, every triumph, every stretch mark, every kiss, every scar. I strive to make you proud. I love YOOOUUUU!!!"
