Beyonce's doting husband Jay-Z led the crowd at Budweiser's Made In America festival in a rendition of Happy Birthday for his superstar wife on Sunday night (03Sep17).

The Formation singer, who turned 36 on Monday, was serenaded by her man and the audience during the rapper's performance at the festival in Philadelphia.

She kickstarted her birthday weekend on Saturday, reportedly arriving at the festival with her two-month-old twins Rumi and Sir and daughter Blue to support the 99 Problems rapper and her sister, Cranes in the Sky singer Solange, who also performed, according to E! News. The couple's mothers also attended the event as the star held court in a private family area.

In pictures obtained by the news outlet, Beyonce was seen looking radiant as she posed for a snap with Bodak Yellow rapper Cardi B, wearing a puff-sleeved Gucci jacket, baseball cap and hotpants.

On Sunday, during Jay's headline set, The Story of O.J. rapper gave a shout out to his wife ahead of her impending birthday - drawing cheers from the crowd.

"Shout out to Beyonce. Beautiful Bey is in the house tonight. Happy Birthday my love," gushed the 47-year-old Brooklyn native in the video posted on Instagram by The Shade Room, before urging the crowd to sing Happy Birthday to his wife.

According to editors at E! News, Beyonce and Blue were spotted dancing and smiling as they listened to Jay perform songs from his new album 4:44. The mother-of-three also took in sets by Cardi B and Migos, and she and Jay cosied up to watch group 21 Savage together.
